Question about package installation

Hi, I am working with R on a Mac. I need to use a couple of packages  
that I found on the Web site. I install them using Packages and  
Data: Package Manager. I leave R and come back another time and the  
installed packages are not installed. So I do it again. Not a big  
deal, but is there anyway to make the installation permanent? I want  
to run R through a 3rd party data management software and since the  
installation is not permanent it can't do the analysis through the  
third party software. Thanks.

Mac specific questions are supposed to be directed to the RSIG-Mac  
mailing list. I can say that your description will almost certainly be  
insufficient, since you are clearly using the R.app GUI and (almost)  
all of us who have been doing so get permanent installation when we do  
so. I have not seen a prevous complaint about transient installations  
and I have read the list for several years now.  So read the Posting  
Guide, construct a more explicit description of how you installed R,  
include sessionInfo() and .Libpaths() information and send to the  
correct list.
