[R] Importing Packages Using OS-X

[Matt Davis]

I am trying to import/load some new packages into my R (1.6.2 or 1.5.1) 
program.  Unfortunately there are a lot of problems that seem to occur.  
I cannot seem to sucessfuly  run any of the commands that should import 
the packages.
Some help with this matter would be greatly appreciated.  (A step by 
step process would be the best, especially how to load a predownloaded 
package (*.tar) into R.)
