without: The relative complement or set difference
In AEBilgrau/Bmisc: Biostatistical miscellaneous functions

Description Usage Arguments Value Note Author(s) Examples

The page decribes different interfaces for the relative complement of x with respect to y, i.e. x\y or x minus y. It is faster than

1 2	without(x, y) x %w/o% y

`x`	A character or numeric vector.
`y`	A character or numeric vector.

The functions returns a vector of the elements in x which does not appear in y.

These functions are identical to setdiff but sometimes more easy to use.
