marginal {probs}

Marginal Distributions

Description

Computes the marginal distribution of a set of variables.

Usage

marginal(space, vars = NULL)

Arguments

space

a data frame probability space or a subset of one.

vars

an optional character vector of variable names in space.

Details

If vars is not specified, then marginal() will set vars to be all non-probs columns, which can be useful in the case that it is desired to aggregate duplicated rows.

Value

A data frame with a probs column.
