[R] Filtering few column from one data frame based on another data frame

[Jeff Newmiller]

I suggest you go back to the Introduction to R document supplied with the software and read about indexing.

In particular, pay attention to indexing into a matrix or data frame using data1[rowspec,columnspec] syntax. There are three kinds of row and column specification types, and any of the the three can be used to solve your problem.
