[R-SIG-Mac] .First() function not being executed on R.app startup

[Steven McKinney]

Hi Simon,

Thanks for checking.  I'm not sure
then why mine is not working.

I removed all objects, and set up your
example .First function:


  > rm(list = ls(all = TRUE))
  > ls(all = TRUE)
  character(0)
  > .First <- function() cat(".First was called\n")
  > ls(all = TRUE)
  [1] ".First"
  > .First
  function() cat(".First was called\n")
  > q()

I saved the workspace after q(), then started
R.app again (from the R.app icon in the dock).
The message does not appear, though the .First
function is still there:

I notice that your session does not show a message such as
"[Workspace restored from /Users/stevenmckinney/.RData]"

Something is different about our setup.

Any idea why I get this message and you do not?
Is your .First just saved in
~/.RData ?

Steven,

can you be more specific, please? I cannot reproduce your  
problem, .First works for me just fine:

.First was called

Cheers,
