I`m not sure, but it may be by design. For example, users sometimes use passwords to connections, which one might not want accidentally recorded in a readable file.Hi,This is with a centos 5.3 x86_64 system, using R 2.8.1 (details below).In a directory where R is invoked, at the end of a session R offers to "Save workspace image". Replying yes creates/updates at least two files in the current directory: .Rhistory and .RData. .Rhistory is created with permissions 0600, therefore it effectively ignores umask. In particular, .Rhistory cannot be group-readable, which can be problematic in some environments. This is not the case for .RData (created 0666, modified by umask as usual), so I doubt that the .Rhistory permissions are restrictive by design?

If not, it would be better to create .Rhistory 0666 and let the user control the actual permissions through umask.Regards, Nicolas Thierry-Mieg ***************************** Steps to reproduce: [nthie...@tryo ~]$ mkdir ttt [nthie...@tryo ~]$ cd ttt [nthie...@tryo ttt]$ R <snip copyright and greeting message> > y<-3 > q() Save workspace image?
