plotBLB {BiplotML}R Documentation

Plot a Binary Logistic Biplot using a BiplotML object

Description

Plot the bootstrap binary logistic biplot and draw confidence ellipses on the individuals of an object BiplotML.

Usage

plotBLB(
  x,
  dim = c(1, 2),
  col.ind = NULL,
  col.var = "#00AFBB",
  label.ind = FALSE,
  draw = c("biplot", "ind", "var"),
  titles = NULL,
  ellipses = FALSE,
  endsegm = 0.75,
  repel = TRUE
)

Arguments

x

Object class BiplotML.

dim

Dimensions plot. By default Dim1 and Dim2.

col.ind

Color for the individuals.

col.var

Color for the variables.

label.ind

By default the row points are not labelled.

draw

The graph to draw ("ind" for the individuals, "var" for the variables and "biplot" for the row and columns coordinates in the same graph)

titles

Title for the Biplot

ellipses

If ellipses=TRUE, draw confidence ellipses around the rows.

endsegm

Represents where the segment of a variable ends on the logit probability scale. By default endsegm=0.75

repel

Repel overlapping text labels.

Details

If draw = "ind", then the biplot is plotted only for individuals and if draw = "var" then is plotted only for the variables.

Value

Returns the Biplot of the individuals and variables.
