thanks gabor. It's appreciated. Another question to you and anyone else who might be out there :
My version of R is : platform i686-pc-linux-gnu arch i686 os linux-gnu system i686, linux-gnu status major 2 minor 3.1 year 2006 month 06 day 01 svn rev 38247 language R version.string Version 2.3.1 (2006-06-01) And tonight was the first time I tried to run two interactive versions of R at the same time ( on two different machines but I Don't know if that matters. I can log into various machines ) : An erroroccurs during the loading of my First.R function in the second R session and it says Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library '/u/etlfs/dev/users/leedsmar/res/R/lib/chron/libs/chron.so': /lib/i686/libc.so.6: version `GLIBC_2.3' not found (required by /u/etlfs/dev/users/leedsmar/res/R/lib/chron/libs/chron.so) Error: package/namespace load failed for 'chron' But this is the first time this has ever happened so I'm thinking that it must be due to trying to run two versions of R at the Same time. The session does come up there but obviously my chron and other libraries after that didn't get loaded. Maybe it's not possible to use loibraries at the same time in two different R sessions but I think I used to do this Atleast when I used R in windows before. Thanks. -----Original Message----- From: Gabor Grothendieck [mailto:[EMAIL PROTECTED] Sent: Saturday, October 28, 2006 7:38 PM To: Leeds, Mark (IED) Cc: r-help@stat.math.ethz.ch Subject: Re: [R] labelling of horizontal axis in acf function Its because of the frequency.
