Function for Real to Real transform of Real to Positive functions and its inverse transformation

Description

Compute the the desired transformation for the abs of the input and multiply the output by the sign of the input.

Usage

transfR(x, transf, inverse = FALSE, base = 2)

Arguments

x	numeric
transf	character name of the function that implements the transformation to be applied.
inverse	logical indicating if the inverse of the transformation is to be performed
base	numeric to be considered as the base of the log transformation

Value

numeric with the transformed input

Examples

transfR(-5:5, 'sqrt')
transfR(-5:5, 'log')
plot(function(x) transfR(x, 'log'), -10, 10)
plot(function(x) transfR(x, 'log', base=10),
     -10, 10, col=4, add=TRUE)
x <- -30:30/30
plot(x, transfR(transfR(x, 'log'),
     'log', inverse=TRUE))
