In my case  I had to close R session and reinstall all packages  In that session I worked with large tables  I suspect this might have had the effect

There could be a few things happening here   Start by first figuring out your library location   Sys getenv  R LIBS USER     or   libPaths     We already know yours from the info you gave  C  Program Files R R-3 0 1 library  I believe you have a file in there called  00LOCK   From  install packages      Note that it is possible for the package installation to fail so badly that the lock directory is not removed  this inhibits any further installs to the library directory  or for --pkglock  of the package  until the lock directory is removed manually    You need to delete that file   If you had the pacman package installed you could have simply used p unlock   and the 00LOCK file is removed   You can t install pacman now until the 00LOCK file is removed   To install pacman use   install packages  pacman     There may be a second issue   This is where you somehow corrupted MASS   This can occur  in my experience   if you try to update a package while it is in use in another R session   I m sure there s other ways to cause this as well   To solve this problem try    Close out of all R sessions  use task manager to ensure you re truly R session free  Ctrl   Alt   Delete Go to your library location Sys getenv  R LIBS USER    In your case this is  C  Program Files R R-3 0 1 library Manually delete the MASS package Fire up a vanilla session of R Install MASS via install packages  MASS     If any of this works please let me know what worked

The solution indicated by Guannan Shen has one drawback that usually goes unnoticed   When you run sudo R in order to run install packages   as superuser  the directories in which you install the library end up belonging to root user  a k a   the superuser   So  next time you need to update your libraries  you will not remember that you ran sudo  therefore leaving root as the owner of the files and directories  that eventually causes the error when trying to move files  because no one can overwrite root but themself   That can be averted by running   sudo chown -R yourusername yourusername     in the directory lib that contains your local libraries  replacing yourusername by the adequated value in your installation   Then you try installing once again
