In krzyslom/lex: Keep track of exponentialized and logarithmized values

Description

exp and log returns exponentiated or logharitmized values.

Usage

exp(x)

log(x)

Arguments

x

Numeric.

Details

exp and log functions call the corresponding ones from base package, but also they set new class to values so that they can be checked later for they current state. This makes easier to track if the used values are in their normal or transformated form.

Examples

mini_iris <- iris[c(1, 51, 101), ]
mini_iris
mini_iris$Sepal.Length <- exp(mini_iris$Sepal.Length)
mini_iris$Petal.Width <- log(mini_iris$Petal.Width)
mini_iris
class(mini_iris$Sepal.Length)
class(mini_iris$Petal.Width)
mini_iris$Sepal.Length <- log(mini_iris$Sepal.Length)
mini_iris$Petal.Width <- exp(mini_iris$Petal.Width)
mini_iris
class(mini_iris$Sepal.Length)
class(mini_iris$Petal.Width)
