问题
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.
回答1:
Search the ubuntu repositories. Have you checked the littler package?
回答2:
The main package for R is called r-base. For the scripting and command-line front-end see littler (or r-cran-littler in xenial (16.04LTS) and beyond):
sudo apt-get install littler

The answers posted so far are generally useful, but they don't directly answer the question. I recently had the same question and discovered there is no rscript binary for Ubuntu. The r binary itself is used to execute scripts in batch mode as opposed to the separate rscript binary that I was using in OS X.
It appears you may be able to get an rscript binary from other sources (see http://craig-russell.co.uk/2012/05/08/install-r-on-ubuntu.html#.UwKWzkJdW2Q for example), but I'm not sure why you would need that when simple running "r script.r" from the command line works just fine.

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.
