Make a file writable in order to add new packages

Question

I use Rstudio and try to add new packages through command console.

It fails to install it for this reason

install.packages(\"devtools\"); devtools::i         


        

Answer 1

I ran into this problem. The issue for me was using single quotes instead of double quotes. Using install.packages("foo") worked fine, whereas install.packages('foo') caused this issue.
