Add a label to a logical vector.

This function is mainly for internal use. It adds a label to a logical vector, so that the Percent pseudo-function can ignore it when forming a denominator.

Usage

labelSubset(subset, label)

Arguments

subset

A logical vector describing a subset of the dataset.

label

A character label to use to describe this subset in a call to Equal or Unequal within Percent.

Value

A vector of class "labelledSubset" with the label recorded as an attribute.
