R help - Mar 2009 - sorting by creation time in ls()

When trying to remember what did I do in the session, especially after  
coming back to it after a few days, I'd like to mimic Unix's ls -ltrh  
-- does R retain the timing a certain variable is created?  If not,  
would it make a useful addition, to have ls with an option to sort by  
creation time?

Cheers,
Alexy

R doesn't keep track of when objects were created, so that's not
possible.

If this is important to you, you could look at the 'trackObjs' package,
which does this and also stores individual objects in individual files (and
writes them to the file when they are changed in R).
