nalevs: Recode variables to 0-1 scale

In weights: Weighting and Weighted Statistics

Description

nalevs takes as an input any vector and recodes it to range from 0 to 1, to treat specified levels as missing, to treat specified levels as 0, 1, .5, or the mean (weighted or unweighted) of the levels present after coding.

Usage

nalevs(x, naset=NULL, setmid=NULL, set1=NULL, set0=NULL,
setmean=NULL, weight=NULL)

Arguments

x	A vector to be recoded to range from 0 to 1.
naset	A vector of values of x to be coded as NA.
setmid	A vector of values of x to be recoded to .5.
set1	A vector of values of x to be recoded to 1.
set0	A vector of values of x to be recoded to 0.
setmean	A vector of values of x to be recoded to the mean (if no weight is specified) or weighted mean (if a weight is specified) of values of x after all recoding.
weight	A vector of weights for x if weighted means are desired for values listed for setmean.

Value

A vector of length equal to that of x of class numeric.
