Description

Functions to extract 2D graphical loadings information from mvdalab objects.

Usage

loadingsplot2D(object, comps = c(1, 2))

Arguments

object

an mvdareg or mvdapca object.

comps

a vector or length 2 corresponding to the number of components to include.

## Number of bootstraps set to 500 to demonstrate flexibility
## Use a minimum of 1000 (default) for results that support bootstraping
mod1 <- plsFit(log.RAI ~., scale = TRUE, data = Penta[, -1], 
               ncomp = 2, validation = "oob", boots = 500)

data(iris)
pc1 <- pcaFit(iris)
loadingsplot2D(pc1, comp = c(1, 2))
