back.transform: Reverse previous transformations.

In LiamDBailey/MyFuncs:

Description

Reverse transformations applied by the 'transform' function. Can be applied to a numeric vector of any length.

Usage

back.transform(x, y, type = "standard")

Arguments

x	Numeric vector of values to be backtransformed.
y	Numeric vector of original data before transformation.
type	The type of transformation to apply. Can be 'standard': with a mean 0 and sd 1; 'standard.log': with a mean 0 and sd 1 but all values > 0 to allows for future log transformation; 'centre': mean of 0.

Value

A numeric vector of back-transformed data.

Examples

#Transform data with mean 0 and sd 1.
transform_data <- transform(mtcars$disp, type = "standard")

#Back transform all data to the original format
back.transform(x = transform_data, y = mtcars$disp, type = "standard")

#Back transform single value to the original format
back.transform(x = 0, y = mtcars$disp, type = "standard")
