Announcing Packrat

2013-11-14 Jonathan McPherson
We’re excited to announce Packrat, a new tool for managing the packages your R project depends on. If you’ve ever been frustrated by package dependencies, whether juggling the packages needed by your own projects or getting someone else’s project to work, Packrat is for you. Similar in spirit to Bundler, Packrat understands package dependencies and manages them inside a private, project-specific library. Packrat makes your project more isolated, portable, and reproducible. Read more →

Version 1.2 of devtools released

2013-04-17 Hadley Wickham
We’re very pleased to announce the release of devtools 1.2. This version continues to make working with packages easier by increasing installation speed (skipping the build step unless local = FALSE), enhancing vignette handling (to support the non-Sweave vignettes available in R 3.0.0), and providing better default compiler flags for C and C++ code. Also new in this release is the sha argument to source_url and source_gist. If provided, this checks that the file you download is what your expected, and is an important safety feature when running scripts over the web. Read more →

We’re very pleased to announce the release of devtools 1.0. We’ve given devtools the 1.0 marker because it now works with the vast majority of packages in the wild, with this version adding support for S4 and Rcpp. Devtools also has completely revamped code for finding Rtools on windows, including much better error messages if something is wrong with your setup. In celebration of reaching 1.0, devtools now has it’s own webpage, which provides a bit more information about why you might want to use it. Read more →

New version of devtools: 0.8

2012-09-16 Hadley Wickham
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.
