pseudoLog: The Signed Pseudo Logarithm

In paodan/funcTools: some useful function tools in practice

The Signed Pseudo Logarithm

Description

The domain of logarithm function is >0. However, sometimes it is required to transform numbers using sort of "signed logarithm". The pseudoLog function can achieve this goal.

Usage

pseudoLog(x, base = 10, sigma = 1, inverse = FALSE)

Arguments

x	numeric value or vector that need to transform.
base	base of logarithm.
inverse	whether the inverse function of pseudoLog is applied.
Scaling	factor for the linear part of pseudo-log transformation.

Examples

## Not run: 
x = c(-10^(4:1), 0, 10^(1:4))
y = pseudoLog(x)
print(y)
z = pseudoLog(x, inverse = TRUE)

## End(Not run)
