Source: R/notin.R

%nin% is the complement to %in%. It looks which values in x do not match (hence, are not in) values in y.

x %nin% y

Arguments

x

Vector with values to be matched.

y

Value

A logical vector, indicating if a match was not located for each element of x, thus the values are TRUE or FALSE and never NA.
