I'm trying to install some basic packages in R, but it shows me this message:
> install.packages("rmarkdown")
Warning in install.packages :
'lib = "C:/Program Files/R/R-3.2.2/library"' is not writable
Warning in install.packages :
cannot create dir 'C:\Users\׳׳׳¢׳“', reason 'Permission denied'
Error in install.packages : unable to create ‘C:/Users/׳׳׳
¢׳“/Documents/R/win-library/3.2’
I tried to change the folder to writable, but it did not help. Anyone knows what the problem is?
