scaleDataFrame: Standardize quantitative variables in a data frame

In DAMisc: Dave Armstrong's Miscellaneous Functions

Description

This function standardizes quantitative variables in a data frame while leaving the others untouched. This leaves not only factors, but also binary variables (those with values 0, 1, or NA).

Usage

scaleDataFrame(data, numsd = 1, nvals_fac = 11, exclude = NULL)

Arguments

data	A data frame.
numsd	Number of standard deviations to divide by - defaults to 1.
nvals_fac	Number of unique values required to standardize - variables with fewer than 'nvals_fac' unique values will not be standardized.
exclude	A character vector of names of variables to exclude from the standardization.

Value

A data frame with standardized quantitative variables
