Hi, I run Rscript from the command line (bash). My OS is the following
$ cat /etc/redhat-release CentOS release 5 (Final) $ uname -a Linux selenium.cluster 2.6.18-53.1.13.el5 #1 SMP Tue Feb 12 13:02:30 EST 2008 x86_64 GNU/Linux $ dmesg | grep gcc Linux version 2.6.18-53.1.13.el5 (mockbu...@builder6.centos.org) (gcc version 4.1.2 20070626 (Red Hat 4.1.2-14)) #1 SMP Tue Feb 12 13:02:30 EST 2008 I can use savehistory in an R session (that is after the R prompt '>'). My file 'savehistory.R' only have the following three lines. f=tempfile() f savehistory(f) I run the command 'Rscript savehistory.R' from the bash command line, which gave me the error I showed in my previous email. Can somebody try if he/she receives the save error?
