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.

# S4 method for Splits,Splits
match(x, table, nomatch = NA_integer_, incomparables = NULL)

in.Splits(x, table)

match(x, table, nomatch = NA_integer_, incomparables = NULL)

# S4 method for Splits,Splits
%in%(x, table)

## Arguments

x, table

Object of class Splits.

nomatch

Integer value that will be used in place of NA in the case where no match is found.

incomparables

Ignored. (Included for consistency with generic.)

## Value

match() returns an integer vector specifying the position in table that matches each element in x, or nomatch if no match is found.

## Details

in.Splits() is an alias for %in%, included for backwards compatibility. It will be deprecated in a future release.

Corresponding base functions are documented in match().
