data.frame is not the same as a matrix in R. Have a look at the R
Intro manual for an overview, or read the man pages for ?data.frame

Not enough info at this stage to help, I'm afraid.

If you have a column (which would be a vector) that acts as the
primary key, you can use the intersect() function to find all ids that
appear in both.
