[R] Generating R plots via Ruby CGI - solved

[Michael Richardson]

My original problem was an inability to generate R plots using the  
following scenario:

1.  HTML page sends data to Ruby CGI

2.  Ruby CGI passes on data to R plotting script, which generates a plot

3.  Ruby CGI passes plot back to user

With help from Scott Sherrill-Mix on this list and from a local friend  
at my institution, the confusing server message I was getting went  
away after fixing the permissions on the folder in the webserver  
containing my code:

> sudo chmod 775 gsa
> sudo chown mrich:www gsa
