In IntervalQuestionStat: Tools to Deal with Interval-Valued Responses in Questionnaires

Convert a real number into a degenerate interval

Description

This function allows to coerce a real number stored as a single numeric object to a degenerate interval formed only by this real number saved as an IntervalData instance.

Usage

## S4 method for signature 'numeric'
as.IntervalData(object)

Arguments

object

A single real number stored as a single numeric object.

Details

Single real numbers could be seen as particular cases of interval-valued data where each interval's lower and upper bounds are equal or, alternatively, its spread is zero.

Value

This function returns a degenerate interval saved as an object of class IntervalData.
