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

Just run RStudio as an administrator. Right-Click on it and choose run as Administrator

Answer 2

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.

Answer 3

As i have found out that disabling the Ransomware protection on Window Defender allows me to write in the directory.

This solved the problem. Hope it works for you.

Answer 4

Changing the security setting on the R folder to "full control" fixed this for me. See the third posting down at this link for step by step instructions: Unable to update R packages in default library on Windows 7
