[R] remove from column a group of elements I have in another vector

[Sarah Goslee]

You can probably do it with not in in R too:
for a data frame x where you want to remove rows where values in
column A are not in the vector y:

x[!(x$A %in% y), ]

If you'd provided a reproducible example, I could give code that works
in your particular circumstance.
