Dear R-list,
I have a problem which I think is quite basic, but so far google has
not
helped me.
I have two vectors like this:
vector_1 <- c(Belgium, Spain, Greece, Ireland, Luxembourg,
Netherlands,
Portugal)
vector_2 <- c(Denmark, Luxembourg)
I would like to find the elements in vector_1 that are not in vector_2
?"%in%"
# the help page for %in% also defines a %w/o% operator as a worked
example.
so that i get a vector with these countries: Belgium, Spain, Greece,
Ireland, Netherlands, Portugal.
Thanks a lot,
Thomas
