I personally prefer this behavior as the scripts I write usually
reside in the same directory (or in a consistent relative path) to
where the relevant data files are.  That way I don't have to put any
full paths in my scripts and they are easier to send to others.

You can easily change both of these things.  The manual covers how to
change Key Equivalents (shortcuts) here
<http://manual.macromates.com/en/bundles>

To change the working directory behavior, open up the R bundle in the
bundle editor and select the command (little green circle) named
"R.app".  Change the following line from:

		  -e 'end run' -- "$rawText" "$curDir"

to:

		  -e 'end run' -- "$rawText" ""

In two seconds of testing, that did the trick on my system.
