Plot.CA: Graphs of the simple (CA) and multiple correspondence analysis (MCA).

Description

Graphs of the simple (CA) and multiple correspondence analysis (MCA).

Usage

Plot.CA(CA, titles = NA, xlabel = NA, ylabel = NA, size = 1.1, 
        grid = TRUE, color = TRUE, linlab = NA, axes = TRUE,
        savptc = FALSE, width = 3236, height = 2000, res = 300, 
        casc = TRUE)

Value

Returns several graphs.

Arguments

CA

Data of the CA function.

titles

Titles of the graphics, if not set, assumes the default text..

xlabel

Names the X axis, if not set, assumes the default text.

ylabel

Names the Y axis, if not set, assumes the default text.

size

Size of the points in the graphs.

grid

Put grid on graphs (default = TRUE).

color

Colored graphics (default = TRUE).

linlab

Vector with the labels for the observations.

axes

Plots the X and Y axes (default = TRUE).

savptc

Saves graphics images to files (default = FALSE).

width

Graphics images width when savptc = TRUE (defaul = 3236).

height

Graphics images height when savptc = TRUE (default = 2000).

res

Nominal resolution in ppi of the graphics images when savptc = TRUE (default = 300).

casc

Cascade effect in the presentation of the graphics (default = TRUE).
