[R] Difficulty with saving .Rhistory

[T]

Current systems

    OS: RedHat SE Linux 5.7, fully patched
    R: R-2.13.1


I am a new R user.


The R installation needs to be very tight because I plan to use it after I am employed on Internet facing systems to analyse firewall and filesystem log data.  Everything to my knowledge regarding R installed correctly.  I saw no warnings until saving THE WORKSPACE.


NON-ROOT OUTPUT CURRENTLY YIELDS THE FOLLOWING ERROR
> q()
Save workspace image? [y/n/c]: y
Warning message:
problem in saving the history file '.Rhistory'
[Object at localhost R]$



The sitrep...


------------------------------------------------------------------------------
INITIAL NON-ROOT OUTPUT WAS THE FOLLOWING
> q()
Save workspace image? [y/n/c]: y
Error in gzfile(file, "wb") : cannot open the connection
In addition: Warning message:
In gzfile(file, "wb") :
  cannot open compressed file '.RDataTmp', probable reason 'Permission denied'
>
> q()
Save workspace image? [y/n/c]: n
Warning message:
In file.remove(outfile) :
  cannot remove file '.RDataTmp', reason 'No such file or directory'


INITIAL ROOT WAS THE FOLLOWING:
>
> q()
Save workspace image? [y/n/c]: y
[root at localhost ~]#


Here is what I did, which I thought would fix everything:

[root at localhost ~]# groupadd -g 666 r_users
[root at localhost ~]# usermod --groups r_users Object
[root at localhost ~]# cat /etc/group | grep r_users
r_users:x:666:Object

[root at localhost ~]# chown -R root:r_users /var/R/R-2.13.1
[root at localhost ~]# 
[root at localhost ~]# find /var/R/R-2.13.1 -type d | xargs chmod g+rwx




Note that I have gREpped for the .RDataTmp file and any variation between "R[Dd]ata" and I see nothing being written but the warnings have stopped...so maybe I am not generating anything to save the workspace.


Now, when using a non-root account I have an issue with the .Rhistory file in that I have the following warnings.

ROOT NOW YIELDS THE FOLLOWING:
> q()
Save workspace image? [y/n/c]: y
[root at localhost ~]#


NON-ROOT OUTPUT NOW YIELDS ANOTHER ERROR
> q()
Save workspace image? [y/n/c]: y
Warning message:
problem in saving the history file '.Rhistory'
[Object at localhost R]$
