Rscript on ubuntu

Question

Where can I install Rscript from? I need to run an R script from a php file using exec. However I need to install Rscript first.

Answer 1

I tried running Rscript in a fresh ubuntu installation (16.04.2 LTS) and got:

The program 'Rscript' is currently not installed. You can install it by typing: sudo apt install r-base-core

so, naturally, i ran sudo apt install r-base-core.

installation took a couple of minutes.

Later, i needed to install an R package, and realized i needed an R shell for that. running r returned:

The program 'r' is currently not installed. You can install it by typing: sudo apt install r-cran-littler

Again, i followed, this time it was quite faster.

I don't know if these are the correct steps to take (or why they would be wrong), but it's what the system led me to do.
