R help - Dec 2008 - How do I reload sessions from a non-default directory in OS X?

i use the GUI version of R on OS X.  I launch it by double-clicking on the R
icon.  The process always starts in my home directory which means that the
only .RData file that is ever read in is the one in my home directory.  I
would instead like to have different R sessions saved in different
directories, but I can't figure out how to do this.

A workaround is to use the shell version of R and always change to the
directory containing my saved session before launching, but I prefer to use
the GUI version.

Is there a command to tell R to load a session from a particular location?
How do other people with Macs do this?

?load

(It's not Mac-specific.)

If you want to clean out the workspace you could use:

rm( ls() )

You can also associate file types with your R.app.

In the

 	R for Mac OS X FAQ

(available in the Help menu)

see
 	4.5.4 Misc Menu
and
 	4.5.5 Workspace Menu



This is an R-sig-mac question, so posting there would have been preferred.

You can use setwd() to change the working directory.
