R 3.1.2 release (and upgrading for Windows users)

R 3.1.2 (codename “Pumpkin Helmet“) was released last week. You can get the latest binaries version from here. (or the .tar.gz source code from here). The full list of new features and bug fixes is provided below.

Upgrading to R 3.1.2 on Windows

If you are using Windows you can easily upgrade to the latest version of R using the installr package. Simply run the following code:

# installing/loading the latest installr package:
install.packages("installr"); library(installr) #load / install+load installr
 
updateR() # updating R.

Running “updateR()” will detect if there is a new R version available, and if so it will download+install it (etc.).

I try to keep the installr package updated and useful, so if you have any suggestions or remarks on the package – you are invited to leave a comment below.

If you use the global library system (as I do), you can run the following in the new version of R:

New.R.RunMe()

CHANGES IN R 3.1.2:

David smith mentioned in his post some of the main changes, writing:

[...] improvements for the log-Normal distribution function, improved axis controls for histograms, a fix to the nlminb optimizer which was causing rare crashes on Windows (and traced to a bug in the gcc compiler), and some compatibility updates for the Yosemite release of OS X on Macs.

And here is also the full list:

Updating R (on Windows) through a menu-bar: installr 0.9 released on CRAN

In preparation for the upcoming release of R 3.0.0, a new release 0.9 of installr is now on CRAN.

The package can be installed and loaded using:

# installing/loading the package:
if(!require(installr)) { 
install.packages("installr"); require(installr)} #load / install+load installr

The new version includes various bug fixes (as can be seen in the NEWS file) and new functions and features. The most user visible feature is that from now on, whenever loading installr in the Rgui, it will add a new menu-bar for updating your R version (the menu is removed when the package is detached).

When choosing to update R, a new GUI based system will guide you step by step through the updating process. It will first check if a newer version of R is available, if so, it will offer to show the latest NEWS of that release, download and install the new version, and copy/move your packages from the previous library folder, to the one in the new installation. If you have a global library folder, you can simply stop the updating once your new R is installed, and continue as you would otherwise (in the future, I intend to update the package to also allow it to deal with people using a global library folder).

installr_updateR_noupdate_needed

(for using {installr} to update R through R terminal, see my previous post: Updating R from R (on Windows) – using the {installr} package)

Another new feature is the “installr()” function (which can also be run through the menubar), running it will open a window with a list of software you can download and install using the installr package (From Rtools and RStudio to pandoc and MikTeX).

I hope you’ll enjoy this new release, and as always – please let me know in the comments (or via e-mail) if you come across any bugs or have suggestions for new features.
