I am using ubuntu 14.04. I have a problem installing Rcpp after I installed MRO 3.2.3 only to find out that the RevoMath lib did not install. So I had to remove and reinstall R but did not reinstall RStudio.

I researched what I could and read Dirk E's post on R CMD SHLIB which led me to this answer post listed below.

I tried installing with your code and it looked like it was going to work but eventually got the same error as posted below (although I did not try to install Rcpp from the terminal using this method yet).

Any help would be greatly appreciated.

Error when installing Rcpp in RStudio on ubuntu 14.04:

installing source package ‘Rcpp’ ...

I think the error is

problem copying ./NAMESPACE to /home/briangriner/R/x86_64-pc-linux-gnu-library/3.2/Rcpp/NAMESPACE: Permission denied

Check the permissions on that Rcpp directory, or just remove it and reinstall Rcpp. As you're on Ubuntu you can also install the (probably a little older) binary package r-cran-rcpp.

  • Thank you for your reply. The permission is root on Rcpp and a couple other packages (like gbm?). I'll try this and let you know. Thanks again. – Brian Griner Jan 27 '16 at 04:37
  • It worked. Used the command rm -r Rcpp and then reinstalled Rcpp in RStudio and am back in business. Thanks again. – Brian Griner Jan 27 '16 at 05:17
