The install packages command looks through the  libPaths variable  Here s what mine defaults to on OSX    gt   libPaths    1    Library Frameworks R framework Resources library    I don t install packages there by default  I prefer to have them installed in my home directory  In my  Rprofile  I have this line    libPaths    Users tex lib R      This adds the directory   Users tex lib R  to the front of the  libPaths variable

This is documented in the  R Installation and Administration  manual that came with your installation   On my Linux box   R gt   libPaths    1    usr local lib R site-library    usr lib R site-library         3    usr lib R library             R gt     meaning that the default path is the first of these  You can override that via an argument to both install packages    from inside R  or R CMD INSTALL  outside R    You can also override by setting the R LIBS USER variable

Thanks for the direction from the above two answerers  James Thompson s suggestion worked best for Windows users    Go to where your R program is installed  This is referred to as R Home in the literature  Once you find it  go to the  etc subdirectory   C  R R-2 10 1 etc  Select the file in this folder named Rprofile site  I open it with VIM  You will find this is a bare-bones file with less than 20 lines of code  I inserted the following inside the code     my custom library path  libPaths  C  R library      The comment added to keep track of what I did to the file   In R  typing the  libPaths   function yields the first target at C  R Library   NOTE  there is likely more than one way to achieve this  but other methods I tried didn t work for some reason
