In liver: "Eating the Liver of Data Science"

Min-Max scaling of numerical variables

Description

Performs Min-Max tranformation for numerical variables.

Usage

minmax(x, col = "auto", min = NULL, max = NULL, na.rm = FALSE)

Arguments

x	a numerical vector, matrix or data.frame.
col	a character vector of column names or indices. If "auto", all numeric columns will be transformed. If "all", all columns will be transformed.
min	a numerical value or vector indicating the minimum value(s) to use for Min-Max tranformation; if NULL, the default is based on x.
max	a numerical value or vector indicating the maximum value(s) to use for Min-Max tranformation; if NULL, the default is based on x.
na.rm	a logical value indicating whether NA values in x should be stripped before the computation proceeds.

Value

transformed version of x.
