Format aesthetics for the category level points

This function allows the user to format the aesthetics for the category level points (CLPs).

CLPs (bp,  which = 1:ncol(bp$Xcat), col = "black", cex = 0.6)

Arguments

bp

an object of class biplot.

which

a vector containing the columns or variables for which the CLPs should be displayed, with default 1:ncol(Xcat).

col

the colour(s) for the CLPs, with default black.

cex

the character expansion(s) for the CLPs, with default 0.6.

Value

The object of class biplot will be appended with a list called CLP.aes containing the following elements A list with the following components is available:

which

a vector containing the columns or variables for which the CLPs are displayed.

col

the colour(s) of the CLPs.

cex
