[R] Merge function - Return NON matches

[Steve Lianoglou]

Hi,

As Sarah reiterated -- it'd *really* be helpful if you give us data we
can actually work with.

That having been said:

You're original email said you had a "list" that contains CLAIM_NO's
you want to exclude.

Is `hrc78_clm_no` this "list" -- does it only have claim_no's? passing
a list into the subset call after `%in%` won't work.

If you do `no <- unlist(hrc_78_clm_no`, do you get a character vector
of claim numbers you want to exclude? If so, then `subset(whatever,
!CLAIM_NO %in% no)` should work.

HTH,
