Hi,
 
I have 4 huge tables on which i want to do a PCA analysis and a kmean clustering. If i run each table individually i have no problems, but if i want to run it in a for loop i exceed the memory alocation after the second table, even if i save the results as a csv table and i clean up all the big objects with rm command. To me it seems that even if i don't have the objects anymore, the memory these objects used to occupy is not cleared. Is there any way to clear up the memory as well? I don't want to close R and start it up again. Also i am running R under Windows.
 
thanks,
 
Monica
