R help - Oct 2009 - Intersection an Sum between list and matrix

Hello,

I need to do an intersection between the list elements (partitionslist) and
the columns and rows of a matrix (mm), so that the result will be the sums
of the rows and columns.


Thanks a lot,

Romildo Martins

Example

1.The Intersection and sum betweeen partitionslist[[1]][[2]] and mm is
indicated in bold.
2.The Intersection and sum betweeen partitionslist[[1]][[2]] and mm is
indicated in red italic.
