[R] R equivalent to MATLAB's "whos" Command?

[andrew]

I saw this in
http://groups.google.com.au/group/r-help-archive/browse_thread/thread/7dca300a7fde5286/718dc5f1405618c9?lnk=gst&q=sort(+sapply(ls()%2Cfunction(x){object.size(get(x))}))#718dc5f1405618c9

The command is something like

sort( sapply(ls(),function(x){object.size(get(x))}))

very useful, so I have added it to my .First function
