Create a bipl5 specification object

init_biplot() stores the raw data and preprocessing options needed to construct a biplot later with scale_mds(). It does not perform any ordination itself. When data is a data frame containing both numeric and non-numeric columns, only the numeric columns are used for the biplot calculation, while the full data frame is retained for later formatting steps such as format_samples().

Usage

init_biplot(data, center = TRUE, scale = FALSE)

Arguments

data

A matrix or data frame. If a data frame contains non-numeric columns, they are stored but excluded from the ordination input.

center

Logical; should numeric variables be centered before analysis?

scale

Logical; should numeric variables be scaled before analysis?

Value

An object of class bipl5_spec.
