R 3.2.1 (codename “World-Famous Astronaut”) was released yesterday. 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 3.2.1 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 in Rgui:
install.packages("installr") # install 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.). There is also a step by step tutorial (with screenshots) on how to upgrade R on Windows, using the installr package.
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 open an issue in the github page.
CHANGES IN R 3.2.1:
utf8ToInt()now checks that its input is valid UTF-8 and returns
NAif it is not.
type = "both"with
repos = NULLif it can infer the type of file.
nzchar(x)gain a new argument
keepNAwhich governs how the result for
xis determined. For the R 3.2.x series, the default remains
FALSEwhich is fully back compatible. From R 3.3.0, the default will change to
keepNA = NAand you are advised to consider this for code portability.
news()more flexibly extracts dates from package ‘NEWS.Rd’ files.
lengths(x)now also works (trivially) for atomic
xand hence can be used more generally as an efficient replacement of
sapply(x, length)and similar.
- The included version of PCRE has been updated to 8.37, a bug-fix release.
diag()no longer duplicates a matrix when extracting its diagonal.
as.character.srcref()gains an argument to allow characters corresponding to a range of source references to be extracted.
