\name{rescale} \alias{rescale} \title{Function to convert scores to ``conventional " metrics} \description{Psychologists frequently report data in terms of transformed scales such as ``IQ" (mean=100, sd=15, ``SAT/GRE" (mean=500, sd=100), ``ACT" (mean=18, sd=6), ``T-scores" (mean=50, sd=10), or ``Stanines" (mean=5, sd=2). The \code{\link{rescale}} function converts the data to standard scores and then rescales to the specified mean(s) and standard deviation(s). } \usage{ rescale(x, mean = 100, sd = 15,df=TRUE) } %- maybe also 'usage' for other objects documented here. \arguments{ \item{x}{A matrix or data frame } \item{mean}{Desired mean of the rescaled scores- may be a vector} \item{sd}{Desired standard deviation of the rescaled scores} \item{df}{if TRUE, returns a data frame, otherwise a matrix} } \value{A data.frame (default) or matrix of rescaled scores. } \author{ William Revelle } \seealso{ See Also \code{\link{scale}} } \examples{ T <- rescale(attitude,50,10) #all put on same scale describe(T) T1 <- rescale(attitude,seq(0,300,50),seq(10,70,10)) #different means and sigmas describe(T1) } \keyword{ multivariate }% at least one, from doc/KEYWORDS \keyword{ models }% __ONLY ONE__ keyword per line \keyword{univar}
