Well, you could try it to see what happens...
First look at:
b$ansologin%in%quit
then
!(b$ansologin%in%quit)
and finally
b[!(b$ansologin%in%quit),]
You could also read the help
?!
?%in%
and the Intro to R manual that came with R when you installed it.

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
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.
