R help - Dec 2008 - match

Hi, I would like to check which rows of 'types.prev' matrix pop up in
'types', following R in-built procedure. I tried 'match'
function but it
works in case of the one dimensional vectors.
Will appreciate any suggestions. 
best, robert

You could first apply paste

apply(types, 1, paste, collapse=':')

and then match.
