I'm struggling to install the package "psych".
I started to use the command install.packages("psych"). The download started and the result was the following:
Installing package into ‘C:/Users/Username/Documents/R/win-library/3.5’
(as ‘lib’ is unspecified)
also installing the dependency ‘mnormt’
trying URL 'https://cran.rstudio.com/bin/windows/contrib/3.5/mnormt_1.5-5.zip'

Error in install.packages : cannot open file 'C:/Users/Username/Documents/R/win-library/3.5/file41147bc27f90/mnormt/CITATION': Permission denied
After that I searched for results. I disabled my firewall. Also I started RStudio with admin rights. A Suggestion was to install the package in R (not R Studio)
There I tried to install it again. The outcome was the following:
Installing package into ‘C:/Users/Username/Documents/R/win-library/3.5’
(as ‘lib’ is unspecified)

Do you have any other idea how to fix that? Is there something wrong with the unzip-program?
Can you do .libPaths() ?
Maybe the .libPaths() doesnt map the correct location (if you are not the administrator)
Try .libPaths(.libPaths()[2]) then try install.packages("psych") again.
