Ploting PCA in a 3D space

Description

Methdo to draw a plot for samples using three PC contained in an ExposomePCA

Usage

plot3PCA(
  object,
  cmpX,
  cmpY,
  cmpZ,
  phenotype,
  main,
  angle = 35,
  pch = 16,
  legend = TRUE,
  plines = TRUE
)

Arguments

object	An onbject of class ExposomePCA
cmpX	Component to be placed at X axis
cmpY	Component to be placed at Y axis
cmpZ	Component to be placed at Z axis
phenotype	Used to color samples by phentoype
main	Title for the plot
angle	(default 35) angle between x and y axis.
pch	(default 16) plotting "character", i.e. symbol to use.
legend	(default TRUE) If TRUE shows the legend.
plines	(default TRUE) If TRUE it draws the lines from each dot to the base plane.
