## R updated

haraldschilly • • r

Dear R users!

We’ve switched our default R to be the “official” one from https://www.r-project.org/. Therefore the default R version has been updated from version 3.2.4 to the most recent one 3.3.2.

This is a quite significant update from the one in SageMath, hence this notice. If for some reason you still need to work with the older version of R in SageMath, do this:

1. In the command-line use R-sage instead of R and Rscript-sage instead of Rscript.

2. In Jupyter notebooks there are two R kernels: the newer “R (R-Project)” and “R (SageMath)” for the version shipped with SageMath.

Regarding libraries, we installed all the ones we know about and many more. In total, there are 557 R libraries (1.3GB) available. Is something that you need still missing? Email [email protected].
