I have a script that sometimes produces the following error: Error in assign(".target", method at target, envir = envir) : formal argument "envir" matched by multiple actual arguments Do you think this is a memory issue? I don't know what else it could be as it doesn't always occur even if the script is run with exactly the same data. Does rm() actually free up memory?

Freeing up memory can be done using gc(). cheers and hth, Paul -- Drs. Paul Hiemstra Department of Physical Geography Faculty of Geosciences University of Utrecht Heidelberglaan 2 P.O.
