[R] Fw: Difficulty with saving .Rhistory

Wed Sep 14 23:05:53 CEST 2011

HTH,

Hahaha, not sure why but I must have filled out T, but I thought that I filled the name out as Tommy...it truncated somewhere.  TC... "Theodore Calvin" the chopper pilot from Vietnam on Magnum PI?   ;-)  Nope, not me.

Sorry all!  I fixed it.  It was that the group was also not root.  I've included the notes in case anyone else runs in to this issue.

What I will do is to try and communicate with the SE LInux guys to see if there is anything that needs to be done to tighten it up using SE Linux security policies.  I am going to have to reinstall in any case since I gave the resource g+w on all the directories in the filesystem so that it could write to the directories.  MY BAD!  Hahaha...

NOTE!

Hello T (short for TC, no doubt),

It appears to me that you're trying to run as a user in the /root/
directory.  Move to a directory down from /home/ and I think you'll
find it works.  

If my guess is incorrect, perhaps if you provide a long list of the
working directory and we'll see what's going on with the permissions.

HTH
