Scale a Displayr Variable Set

Description

Given a Displayr Variable Set or Q Question, performs a specified scaling on the data; first converting any categorical variables to numeric as necessary.

Usage

ScaleVariableSet(
  data,
  type = c("standardize", "center", "unit", "rank"),
  within.case = FALSE
)

Arguments

data	A Displayr Variable Set or Q Question: A numeric or factor vector, or a data.frame containing either all numeric columns or all factor columns.
type	Character string specifying the type of scaling to perform; one of "standardize" (the default), "center", "rank", or "unit".
within.case	Logical; should the scaling be performed within case (rows) or variables (columns). An error is thrown if TRUE and data contains only one variable.

Value

A numeric vector if data contains only a single variable or a data.frame containing the scaled values.
