Usage
"plot"(x, axes = c(1, 2), choix = c("ind", "freq", "quali.var", "quanti.var"), conf.ellip = FALSE, contr.ellipse = 3, xlim = NULL, ylim = NULL, col.ind = "black", col.freq = "darkred", col.quali = "blue", col.quanti = "blue", label = TRUE, lim.cos2.var = 0, title = NULL, palette = NULL, autoLab = c("auto", "yes", "no"), new.plot = FALSE, select = NULL, unselect = 0.7, shadowtext = FALSE, ...)
Arguments
x
an object of class CaGalt
axes
a length 2 vector specifying the components to plot
choix
the graph to plot ("ind" for the individuals, "freq" for the frequencies, "quali.var" for the categorical variables, "quanti.var" for the quantitative variables)
conf.ellip
boolean (FALSE by default), if TRUE, draw ellipses around the frequencies and the variables
contr.ellipse
the confidence ellipses were drawn for the frequencies with a contribution higher than X times of mean contribution on the 2 dimensions of your plot (by default 3)
xlim
range for the plotted 'x' values, defaulting to the range of the finite values of 'x'
ylim
range for the plotted 'y' values, defaulting to the range of the finite values of 'y'
col.ind
a color for the individuals (by default "black")
col.freq
a color for the frequencies (by default "darkred")
col.quali
a color for the categories of categorical variables (by default "blue")
col.quanti
a color for the quantitative variables (by default "blue")
label
the labels are drawn (by default TRUE)
lim.cos2.var
value of the square cosinus under the variables are not drawn
title
string corresponding to the title of the graph you draw (by default NULL and a title is chosen)
palette
the color palette used to draw the points. By default colors are chosen. If you want to define the colors : palette=palette(c("black","red","blue")); or you can use: palette=palette(rainbow(30)), or in black and white for example: palette=palette(gray(seq(0,.9,len=25)))
autoLab
if autoLab="auto", autoLab is equal to "yes" if there are less than 50 elements and "no" otherwise; if "yes", the labels of the drawn elements are placed in a "good" way (can be time-consuming if many elements), and if "no" the elements are placed quickly but may overlap
new.plot
boolean, if TRUE, a new graphical device is created
select
a selection of the elements that are drawn; see the details section
unselect
may be either a value between 0 and 1 that gives the transparency of the unselected objects (if unselect=1 the transparency is total and the elements are not drawn, if unselect=0 the elements are drawn as usual but without any label) or may be a color (for example unselect="grey60")
shadowtext
boolean; if true put a shadow on the labels (rectangles are written under the labels which may lead to difficulties to modify the graph with another program)
