Subject: Remove several numbers from a sequence
In-Reply-To: <1345474508133-4640794.post@n4.nabble.com>
many thanks for lots of different solutions. I have a couple of very large
data frames but using the unique identifier for each row and Arun's solution
zz[is.na(match(zz$z1,xx$x1)),]
has worked perfectly,
Thanks!
