See you in New York City! (http://strataconf.com/big-data-conference-ny-2015)
Five months ago we launched shinyapps.io. Since then, more than 25,000 accounts have been created and countless Shiny applications have been deployed. It’s incredibly exciting to see!
It’s also given us lots of data and feedback on how we can make shinyapps.io better. Today, we’re happy to tell you about some changes to our subscription Plans that we hope will make shinyapps.io an even better experience for Shiny developers and their application users.
New Starter Plan – More active hours and apps, less money
For many people the price difference between the Free and the Basic plan was too much. We heard you. Effective today there is a new Starter Plan for only $9 per month or $100 per year. The Starter Plan has the same features as the Free plan but allows 100 active hours per month and up to 25 applications. It’s perfect for the active Shiny developer on a budget!
More Active Hours for Basic, Standard, and Professional Plans
Once you’re up and running with Shiny we want to make sure even the most prolific developers and popular applications have the active hours they need. Today we’re doubling the number of active hours per month for the Basic (now 500), Standard (now 2,000), and Professional (now 10,000) plans. In practice, very few accounts exceeded the old limits for these plans but now you can be sure your needs are covered.
New Performance Boost features for the Basic Plan
In addition to supporting multiple R worker processes per application, which keeps your application responsive as more people use it, we’ve added more memory (up to 8GB) on Basic plans and above. While the data shows that most applications work fine without these enhancements, if you expect many users at the same time or your application is memory or CPU intensive, the Basic Plan has the performance boost you need. The Basic plan also allows unlimited applications and 500 active hours per month.
Traditionally, the mechanisms for obtaining R and related software have used standard HTTP connections. This isn’t ideal though, as without a secure (HTTPS) connection there is less assurance that you are downloading code from a legitimate source rather than from another server posing as one.
Recently there have been a number of changes that make it easier to use HTTPS for installing R, RStudio, and packages from CRAN:
- Downloads of R from the main CRAN website now use HTTPS;
Downloads of RStudio from our website now use HTTPS; and
It is now possible to install packages from CRAN over HTTPS.
There are a number of ways to ensure that installation of packages from CRAN are performed using HTTPS. The most recent version of R (v3.2.2) makes this the default behavior. The most recent version of RStudio (v0.99.473) also attempts to configure secure downloads from CRAN by default (even for older versions of R). Finally, any version of R or RStudio can use secure HTTPS downloads by making some configuration changes as described in the Secure Package Downloads for R article in our Knowledge Base.
Configuring Secure Connections to CRAN
While the simplest way to ensure secure connections to CRAN is to run the updated versions mentioned above, it’s important to note that it is not necessary to upgrade R or RStudio to achieve this end. Rather, two configuration changes can be made:
- The R
download.file.methodoption needs to specify a method that is capable of HTTPS; and
- The CRAN mirror you are using must be capable of HTTPS connections (not all of them are).
The specifics of the required changes for various products, platforms, and versions of R are described in-depth in the Secure Package Downloads for R article in our Knowledge Base.
Recommendations for RStudio Users
We’ve made several changes to RStudio IDE to ensure that HTTPS connections are used throughout the product:
- The default
download.file.methodoption is set to an HTTPS compatible method (with a warning displayed if a secure method can’t be set);
- The configured CRAN mirror is tested for HTTPS compatibility and a warning is displayed if the mirror doesn’t support HTTPS;
- HTTPS is used for user selection of a non-default CRAN mirror;
- HTTPS is used for in-product documentation links;
- HTTPS is used when checking for updated versions of RStudio (applies to desktop version only); and
- HTTPS is used when downloading Rtools (applies to desktop version only).
If you are running RStudio on the desktop we strongly recommend that you update to the latest version (v0.99.473).
Recommendations for Server Administrators
If you are running RStudio Server it’s possible to make the most important security enhancements by changing your configuration rather than updating to a new version. The Secure Package Downloads for R article in our Knowledge Base provides documentation on how do this.
In this case in-product documentation links and user selection of a non-default CRAN mirror will continue to use HTTP rather than HTTPS however these are less pressing concerns than CRAN package installation. If you’d like these functions to also be performed over HTTPS then you should upgrade your server to the latest version of RStudio.
If you are running Shiny Server we recommend that you modify your configuration to support HTTPS package downloads as described in the Secure Package Downloads for R article.
The Joint Statistics Meetings starting August 8 is the biggest meetup for statisticians in the world. Navigating the sheer quantity of interesting talks is challenging – there can be up to 50 sessions going on at a time!
To prepare for Seattle, we asked RStudio’s Chief Data Scientist Hadley Wickham for his top session picks. Here are 9 talks, admittedly biased towards R, graphics, and education, that really interested him and might interest you, too.
Check out these talks

Visit RStudio at booth #435
In between session times you’ll find the RStudio team hanging out at booth #435 in the expo center (at the far back on the right). Please stop by and say hi! We’ll have stickers to show your R pride and printed copies of many of our cheatsheets.
See you in Seattle!
To paraphrase Yogi Berra, “Predicting is hard, especially about the future”. In 1993, when Ross Ihaka and Robert Gentleman first started working on R, who would have predicted that it would be used by millions in a world that increasingly rewards data literacy? It’s impossible to know where R will go in the next 20 years, but at RStudio we’re working hard to make sure the future is bright.
Today, we’re excited to announce our participation in the R Consortium, a new 501(c)6 nonprofit organization. The R Consortium is a collaboration between the R Foundation, RStudio, Microsoft, TIBCO, Google, Oracle, HP and others. It’s chartered to fund and inspire ideas that will enable R to become an even better platform for science, research, and industry. The R Consortium complements the R Foundation by providing a convenient funding vehicle for the many commercial beneficiaries of R to give back to the community, and will provide the resources to embark on ambitious new projects to make R even better.
We believe the R Consortium is critically important to the future of R and despite our small size, we chose to join it at the highest contributor level (alongside Microsoft). Open source is a key component of our mission and giving back to the community is extremely important to us.
The community of R users and developers have a big stake in the language and its long-term success. We all want free and open source R to continue thriving and growing for the next 20 years and beyond. The fact that so many of the technology industry’s largest companies are willing to stand behind R as part of the consortium is remarkable and we think bodes incredibly well for the future of R.
We’re pleased to announce that the final version of RStudio v0.99 is available for download now. Highlights of the release include:
- A new data viewer with support for large datasets, filtering, searching, and sorting.
- Complete overhaul of R code completion with many new features and capabilities.
- The source editor now provides code diagnostics (errors, warnings, etc.) as you work.
- User customizable code snippets for automating common editing tasks.
- Tools for Rcpp: completion, diagnostics, code navigation, find usages, and automatic indentation.
- Many additional source editor improvements including multiple cursors, tab re-ordering, and several new themes.
- An enhanced Vim mode with visual block selection, macros, marks, and subset of : commands.
There are also lots of smaller improvements and bug fixes across the product. Check out the v0.99 release notes for details on all of the changes.
We’ve completely overhauled the data viewer with many new capabilities including live update, sorting and filtering, full text searching, and no row limit on viewed datasets.
See the data viewer documentation for more details.
Previously RStudio only completed variables that already existed in the global environment. Now completion is done based on source code analysis so is provided even for objects that haven’t been fully evaluated:
Completions are also provided for a wide variety of specialized contexts including dimension names in [ and [[:
We’ve added a new inline code diagnostics feature that highlights various issues in your R code as you edit.
For example, here we’re getting a diagnostic that notes that there is an extra parentheses:
Here the diagnostic indicates that we’ve forgotten a comma within a shiny UI definition:
Code snippets are text macros that are used for quickly inserting common snippets of code. For example, the
fun snippet inserts an R function definition:
If you select the snippet from the completion list it will be inserted along with several text placeholders which you can fill in by typing and then pressing Tab to advance to the next placeholder:
Other useful snippets include:
sourcefor the library, require, and source functions
matfor defining data frames and matrices
eifor conditional expressions
sapply, etc. for the apply family of functions
sgfor defining S4 classes/methods.
See the code snippets documentation for additional details.
Try it Out
RStudio is excited to announce the general availability (GA) of shinyapps.io.
Shinyapps.io is an easy to use, secure, and scalable hosted service already being used by thousands of professionals and students to deploy Shiny applications on the web. Effective today, shinyapps.io has completed beta testing and is generally available as a commercial service for anyone.
As regular readers of our blog know, Shiny is a popular free and open source R package from RStudio that simplifies the creation of interactive web applications, dashboards, and reports. Until today, Shiny Server and Shiny Server Pro were the most popular ways to share shiny apps. Now, there is a commercially supported alternative for individuals and groups who don’t have the time or resources to install and manage their own servers.
We want to thank the nearly 8,000 people who created at least one shiny app and deployed it on shinyapps.io during its extensive alpha and beta testing phases! The service was improved for everyone because of your willingness to give us feedback and bear with us as we continuously added to its capabilities.
For R users developing shiny applications that haven’t yet created a shinyapps.io account, we hope you’ll give it a try soon! We did our best to keep the pricing simple and predictable with Free, Basic, Standard, and Professional plans. Each paid plan has features and functionality that we think will appeal to different users and can be purchased with a credit card by month or year. You can learn more about shinyapps.io pricing plans and product features on our website.
We hope to see your shiny app on shinyapps.io soon!
Sometimes the universe surprises us. In this case, it was in a good way and we genuinely appreciated it.
Earlier this week we learned that the Infoworld Testing Center staff selected RStudio as one of 32 recipients of the 2015 Technology of the Year Award.
We thought it was cool because it was completely unsolicited, we’re in very good company (some of our favorite technologies like Docker, Github, node.js…even my Dell XPS 15 Touch!…were also award winners) and the description of our products was surprisingly elegant – simple and accurate.
We know Infoworld wouldn’t have known about us if our customers hadn’t brought us to their attention.

Shiny version 0.11 is available now! Notable changes include:
- Shiny has migrated from Bootstrap 2 to Bootstrap 3 for its web front end. More on this below.
- The old jsliders have been replaced with ion.rangeSlider. These sliders look better, are easier for users to interact with, and support updating more fields from the server side.
- There is a new
passwordInput()which can be used to create password fields.
eventReactive()functions greatly streamline the use of
actionButtonand other inputs that act more like events than reactive inputs.
For a full set of changes, see the NEWS file. To install, run:
We’ve also posted an article with notes on upgrading to 0.11.
Bootstrap 3 migration
In all versions of Shiny prior to 0.11, Shiny has used the Bootstrap 2 framework for its web front-end. Shiny generates HTML that is structured to work with Bootstrap, and this makes it easy to create pages with sidebars, tabs, dropdown menus, mobile device support, and so on.
The Bootstrap development team stopped development on the Bootstrap 2 series after version 2.3.2, which was released over a year ago, and has since focused their efforts on Bootstrap 3. The new version of Bootstrap builds on many of the same underlying ideas, but it also has many small changes – for example, many of the CSS class names have changed.
In Shiny 0.11, we’ve moved to Bootstrap 3. For most Shiny users, the transition will be seamless; the only differences you’ll see are slight changes to fonts and spacing.
If, however, you customized any of your code to use features specific to Bootstrap 2, then you may need to update your code to work with Bootstrap 3 (see the Bootstrap migration guide for details). If you don’t want to update your code right away, you can use the shinybootstrap2 package for backward compatibility with Bootstrap 2 – using it requires adding just two lines of code. If you do use shinybootstrap2, we suggest using it just as an interim solution until you update your code for Bootstrap 3, because Shiny development going forward will use Bootstrap 3.
Why is Shiny moving to Bootstrap 3? One reason is support: as mentioned earlier, Bootstrap 2 is no longer developed and is no longer supported. Another reason is that there is dynamic community of actively-developed Bootstrap 3 themes. (Themes for Bootstrap 2 also exist, but there is less development activity.) Using these themes will allow you to customize the appearance of a Shiny app so that it doesn’t just look like… a Shiny app.
We’ve also created a package that make it easy to use Bootstrap themes: shinythemes. Here’s an example using the included Flatly theme:
See the shinythemes site for more screenshots and instructions on how to use it.
The shinydashboard package still under development, but feel free to try it out and give us feedback.
