newMean: Computes the Mean of a Set of Variables

In DeducerAlpha: Tools for aggregating scale items

Description

Given a set of variables, some of which may need to be reverse-scored, this function returns a column vector mean of those variables after reverse-scoring those so designated.

Usage

newMean(data, variables = NULL, reversed = NULL, max = NULL, label)

Arguments

data	A data.frame containing the variables in both variables and reversed
variables	Variables to be retained in the dataset but that do not need to be reverse-scored
reversed	Variables to be reverse-scored
max	The maximum possible value for reversed. If the variables in reversed range from 1 to 7, max would be 7. Note that all the items must share the same maximum value.
label	Name to be given to the new mean variable.

Value

A named column vector equal to the mean of a combination of variables and reversed after the latter have been reverse-scored.
