umx_scale: Scale data columns, skipping non-scalable columns

Description

umx_scale applies scale to a data.frame. It scale numeric columns, and is smart enough to skip non-scalable columns (string, factor, etc.).

Usage

umx_scale(df, varsToScale = NULL, coerce = FALSE, attr = FALSE,
  verbose = FALSE)

Arguments

df

A dataframe to scale (or a numeric vector)

varsToScale

(leave blank to scale all)

coerce

Whether to coerce non-numerics to numeric (Defaults to FALSE)

attr

to strip off the attributes scale creates (FALSE by default)

verbose

Whether to report which columns were scaled (default FALSE)

Value

- new dataframe with scaled variables

Details

Also strips-off the attributes which scale adds ("scaled:center" and "scaled:scale" (set attr= TRUE) to keep these.
