PCA.PlotScores: Score plot for the results of PCA.Calculate.

Description

Allows the user to plot a score plot for two or more components. Also allows the user to set advanced labeling options.

Usage

PCA.PlotScores(pr.object, pcs = c(1, 2), labels = "none", custom.labels = NULL, 
dot.class.vector = NULL, col.class.vector = NULL)

Arguments

pr.object

the result of PCA.Calculate

pcs

Which principal components to use for plotting (eg. "1,2" or "1:4")

labels

what type of labels to be used for the scores. Can either be: "none" or "dots" which will plot simple dots, "numerical" which will plot numbers, or "custom" which will plot user defined labels contained in the custom.labels argument.

custom.labels

in case the labels argument is set to "custom", this argument needs to contain a vector of character labels to be used for plotting.

dot.class.vector

NULL by default, in which case all dots are standard dots. A numerical vector can be supplied that defines each dot's symbol type (using R's default number to symbol type conversion).

col.class.vector

NULL by default, in which case all dots are black. A numerical vector can be supplied that defines each dot's color (using R's default number to color conversion).

Value

Only the plot is returned.
