Most times when I attempt to install an R package, I'll get the following error message. The error message I got below occurred when I tried to install a package named "moments". The package was found, downloaded and unpacked but I don't understand why it couldn't be installed. The destination folder does exist. It is not my R working directory though, if that matters.
package ‘moments’ successfully unpacked and MD5 sums checked
Warning in install.packages :
unable to move temporary installation ‘C:\Users\fs103799\Dropbox\R3.3.1\library\file1da0c1d9622a1\moments’ to ‘C:\Users\fs103799\Dropbox\R3.3.1\library\moments’
The downloaded binary packages are in
C:\Users\fs103799\AppData\Local\Temp\Rtmp6ZSV46\downloaded_packages
I am getting the same issue when installing into Dropbox folder while Dropbox is running, exit Dropbox then try to install, it should work.
install.packages("moments", lib = "C:/xxx/Dropbox/")
I have admin rights on the computer.
