Last month we released Shiny, our new R package for creating interactive web applications. The response from the community has been extremely encouraging–we’ve received a lot of great feedback that has helped us to make significant improvements to the framework already! Shiny 0.2.3 on CRAN Starting with Shiny 0.2.3, you can install the latest stable version of Shiny directly from CRAN. Since the initial release, we’ve added some interesting features to Shiny, most notably the ability to offer on-the-fly file downloads. Read more →

Earlier this month a new version of the Rcpp package by Dirk Eddelbuettel and Romain François was released to CRAN and today we’re excited to announce a new version of RStudio that integrates tightly with Rcpp. First though more about some exciting new features in Rcpp 0.10.1. This release includes Rcpp attributes, which are simple annotations that you add to C++ source files to streamline calling C++ from R. This makes it possible to write C++ functions and simply source them into R just as you’d source an R script. Read more →

Say hello to Shiny, a new R package that we’re releasing for public beta testing today. Shiny makes it super simple for R users to turn analyses into interactive web applications that anyone can use. These applications let you specify input parameters using friendly controls like sliders, drop-downs, and text fields; and they can easily incorporate any number of outputs like plots, tables, and summaries. No HTML or JavaScript knowledge is necessary. Read more →

The latest version of lubridate offers some powerful new features and huge speed improvements. Some areas, such as date parsing are more than 50 times faster. lubridate 1.2.0 also fixes those pesky NA bugs in 1.1.0. Here’s some of what you’ll find: Parsers can now handle a wider variety date formats, even within the same vector dates <- c("January 31, 2010", "2-28-2010", "03/31/2000") dates <- mdy(dates) ## [1] "2010-01-31 UTC" "2010-02-28 UTC" "2000-03-31 UTC Stamp lets you display dates however you like, by emulating an example date Read more →

Using the web logs collected when users download RStudio, we’ve prepared the following two maps showing where RStudio is being used, over the whole globe and just within the continental USA. Obviously this data is somewhat biased, as it reflects the number of downloads of RStudio, rather than the number of users of R (which we’d really love to know!). However, based on a month’s worth of data, we think the broad patterns are pretty interesting. Read more →

We’re pleased to announce a new version of devtools, the package that makes R package development easy. The main features in this version are: A complete rewrite of the code loading system which simulates namespace loading much more accurately - this means using load_all is much closer to installing and loading the package. It also compiles and loads C, C++ and Fortran code in the src/ directory. All devtools command now only take a path to a package and default to using the working directory if no path is supplied.

The main changes in this version are to the theming system. There are also a number of enhancements to the theming system that make it easier to modify themes and we’ve renamed a number of functions to have more informative names. Your existing code should continue to work, although you may receive warnings about functions that have been deprecated. Replacing them with new versions is easy. Here are the changes you are likely to encounter: Read more →
