subsetting data set by selecting data which does not match

Question

I have the code

ISL2N=subset(Grouptwo, Grouptwo$Initials %in% ISL$Initials)

Now I want to do subsetting of values in Grouptwo, where Grouptwo$Initials does not match ISL$Initials

Try `subset(Grouptwo, !(Grouptwo$Initials %in% ISL$Initials)` — jake2389, Jan 12 '19 at 21:03

There is a logical NOT operator(!) which gives the opposite value of the result.

Try this:

ISL2N=subset(Grouptwo, !(Grouptwo$Initials %in% ISL$Initials))
