union: Union of Subsets

Description

Calculates the union of subsets of a probability space.

Usage

union(x, ...)

## S3 method for class 'default':
union(x, y, \ldots)

## S3 method for class 'data.frame':
union(x, y, \ldots)

## S3 method for class 'ps':
union(x, y, \ldots)

Arguments

x, y

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

...

further arguments to be passed to or from other methods.

Value

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

Details

This function operates row-wise on dataframes, and element-wise among the outcomes of ps objects. The elements of union(x,y) are those elements in x or y, or both. The definition is taken to match the version in the base package.
