scaleSC {scan}R Documentation

Scaling values of an scdf file

Description

This function scales the measured values of an scdf file. It allows for mean centering and standardization based on each s?ingle-case data set or a scaling across all cases included in an scdf.

Usage

scaleSC(data, var, center = TRUE, scale = FALSE, m = 0, sd = 1,
  grand = TRUE)

Arguments

data

A single-case data frame. See scdf to learn about this format.

var

A character string or a vector of character strings with variable names that should be scaled.

center

If set TRUE, data are mean centered.

scale

If set TRUE, the standard deviation is set.

m

The target mean for centering.

sd

The target standard deviation for scaling

grand

If set TRUE, scaling is based on the mean and standarddeviation of all measurements across all single-cases within the scdf.

Value

An scdf with the scaled values.
