R 3.4.0 released

R 3.4.0 was released some days ago. A compatibility update to RStudio is also available.

The repositories at this site and obviously also at CRAN now contain package binary distributions for R 3.4.x and R 3.3.x.

One major change in this release is that the JIT (just in time) compiler is enabled by default. I have not done any benchmarking yet.

I have written a page explaining how to upgrade your R installation.

The code examples in my book Learn R …as you learnt your mother tongue continue to work as expected. However not all the package updates for R 3.4.0 are yet in CRAN. In package ‘gganimate’ function gg_animate() has been renamed gganimate().

The code examples in our book R for Photobiology: Theory and recipes for common calculations run without problems. Due to recent updates to the packages in my R for Photobiology Suite, used in the book examples, fewer warnings than earlier are triggered.

R 3.3.3 has been released

It is always best to keep R up-to-date. This is not a major release, but instead mostly a bug fix release.

If you are using R on MS-Windows then you can very painlessly upgrade R with package ‘installr’. These are the needed steps, that should be carried out not in RStudio but in RGUI (i.e. double click the R icon on your desktop).

At the console enter:

install.packages("installr") # install
setInternet2(TRUE) # only for R versions older than 3.3.0
installr::updateR() # updating R.


Follow the prompts. I suggest that you copy and update the packages in the library.

February ’17 Tips and Tricks – RStudio

by Sean Lopp If you spend time with an excellent programmer, one thing that immediately jumps out is how quickly she can write code. It often appears to be magic, the number of keystrokes simply can’t equal the number of characters on the screen. The secret: it doesn’t! Most programmers use a series of tricks to
