Hi,

There are multiple threads on this subject on the R-help list, googling 
for "formal argument matched by mutiple actual arguments" lead me to:

http://tolstoy.newcastle.edu.au/R/help/05/08/10698.html

So this is probably not a memory issue. Freeing up memory can be done 
using gc().

cheers and hth,
Paul
