Performs feature scaling such as Z-score and min-max scaling.
scaler(x, scale = c("minmax", "zscore"), col = "auto",
par1 = NULL, par2 = NULL, na.rm = FALSE)transformed version of x.
a numerical vector, a matrix or a data.frame.
a transfer for x.
a character vector of column names or indices. If "auto", all numeric columns will be transformed. If "all", all columns will be transformed.
a numerical value or vector that for the case scale = "minmax" indicating the maximum value(s) and for the case scale = "zscore" indicating the mean value(s).
a numerical value or vector that for the case scale = "minmax" indicating the maximum value(s) and for the case scale = "zscore" indicating the sd value(s).
a logical value indicating whether NA values in x should be stripped before the computation proceeds.
