ggplotScores

Description

Plots the two components defined by pc1, pc2 of the matrix of scores coming from a multivariable analysis, typically a Principal Component Analysis (PCA).

Usage

ggplotScores(
  data,
  pc1 = 1,
  pc2 = 2,
  groups = NULL,
  EV = NULL,
  main = "Scores",
  glabels = FALSE,
  psize = 3,
  gcontour = "ellipse",
  params = list(cellipse = 0.95)
)

Arguments

data	the matrix of scores coming from a multivariable analysis, typically a Principal Component Analysis (PCA)
pc1	the fist component of the matrix of variable loadings to be plotted.
pc2	the second component of the matrix of variable loadings to be plotted.
groups	the vector defining the factorial groups (same dimension as data rows)
EV	Eigenvalues vector
main	the plot main title
glabels	boolean indicating if labels have to be plotted
psize	point size
gcontour	type of contour; possible values are : 'ellipse', 'polygon', 'ellipse2', 'none'
params	parameters depending on the contour type
