It isn't.  Please do read 'An Introduction to R': you can start R with 
--no-restore.

And BTW

isn't correct: it needs to be

rm (list = ls(all=TRUE))

However, I suspect that YM is starting R with a non-writable working 
directory, and (on Windows) the suggestion is that you create a new 
shortcut with the working directory (the 'Start in' property) changed 
to the base directory of your project.

We've seen instances with an all-users adminstrator install of R on 
Windows 7 (but not earlier) that non-administrator users cannot edit 
nor copy the shortcut on their desktop.  This seems to be a bug in 
Windows, so simply create a new one to (e.g.)
c:/Program Files/R/R-2.12.0/bin/i386/Rgui.exe
