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

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.

Hi,

I have a data frame and I would need to remove from one of
the columns a group of elements I have in another vector. How can I do that? I know how to do it with criteria but i would need to do it in a more automatic way....
In SQL I would use  where
---- not in ----

Thank you,
Estefania
