simple.scale: 'Simple' Scaling and Centering

In stevencarlislewalker/multitable: Simultaneous Manipulation of Multiple Arrays of Data

Description

Simpler version of the scale function, which works better for variables in data lists.

Usage

simple.scale(x, center = TRUE, scale = TRUE, simplify = TRUE)

Arguments

x	an R object with numeric data
center	should mean of x be subtracted from x?
scale	should x (centered or otherwise) be divided by its (population) standard deviation?
simplify	should x be first passed through simplify2array?

Details

simple.scale simplifies scale in three ways:

• Treats matrix-like objects as a single variable, rather than several variables (i.e. one per column as in scale).

• Uses the population version of the standard deviation, rather than the sample version.

• Preserves dimensions of arrays of any number of dimensions, rather than collapse to a single column matrix for arrays with three or more dimensions.

• Doesn't bother to check if x is numeric.

For further information, just type simple.scale to see the source (it really is a very simple function).

Value

A scaled version of x (possibly simplified to an array, if simplify = TRUE).
