Set Difference of Subsets Calculates the (nonsymmetric) set difference of subsets of a probability space.

Description

Set Difference of Subsets Calculates the (nonsymmetric) set difference of subsets of a probability space.

Usage

## Default S3 method:
setdiff(x, y, ...)

Arguments

x

vectors, data frames, or ps objects containing a sequence of items (conceptually).

y

vectors, data frames, or ps objects containing a sequence of items (conceptually).

...

further arguments to be passed to or from other methods.

Details

This function operates row-wise on dataframes, and element-wise among the outcomes of ps objects. The elements of setdiff(x,y) are those elements in x but not in y. The definition is taken to match the version in the base package.

Value

A data frame or subset of a probability space of the same type as its arguments.
