match() returns a vector of the positions of (first) matches of splits in
its first argument in its second.
%in% is a more intuitive interface as a binary operator, which returns
a logical vector indicating whether there is a match or not for each
split in its left operand.
match(x, table, ...) # S3 method for Splits match(x, table, ...) # S3 method for list match(x, table, ...) x %in% table # S3 method for Splits %in%(x, table) in.Splits(x, table)
Object of class
nomatch = to provide an integer value that will be
used in place of
NA in the case where no match is found.
match() returns an integer vector specifying the position in
table that matches each element in
nomatch if no match is found.
%in% returns a logical vector specifying which of the splits in
x are present in
in.Splits() is an alias for
%in%, included for backwards compatibility.
It will be deprecated in a future release.
