Factorial Planes Showing the Classes

Description

For objects of class FactoClass it graphs a factorial plane showing the center of gravity of the cluster, and identifying with colors the cluster to which each element belongs.

Usage

plotFactoClass(FC , x=1, y=2, rotx=FALSE, roty=FALSE,
                roweti=row.names(dudi$li),
                coleti=row.names(dudi$co),titre=NULL, axislabel=TRUE,
                col.row=1:FC$k, col.col="blue", cex=0.8, cex.row=0.8, cex.col=0.8,
                all.point=TRUE, Trow=TRUE, Tcol=TRUE, 
                 cframe=1.2, ucal=0,
                cex.global=1, infaxes="out",nclus=paste("cl", 1:FC$k, sep=""),cex.clu=cex.row,cstar=1 )

Arguments

FC object of class FactoClass.
x number indentifying the factor to be used as horizontal axis. Default x=1
y number indentifying the factor to be used as vertical axis. Default y=2
rotx TRUE if you want change the sign of the horizontal coordinates (default FALSE).
roty TRUE if you want change the sign of the vertical coordinates (default FALSE).
roweti selected row points for the graphic. Default all points.
coleti selected column points for the graphic. Default all points.
titre graphics title.
axislabel if it is TRUE the axis information is written.
col.row color for row points and row labels. Default 1:FC$k.
col.col color for row points and row labels. Default "grey55".
cex global scale for the labels. Default cex=0.8.
cex.row scale for row points and row labels. Default cex.row=0.8.
cex.col scale for column points and column labels. Default cex.col=0.8.
cex.clu scale for cluster points and cluster labels. (default cex.row).
all.point if if is TRUE, all points are outlined. Default all.point=TRUE.
Trow if it is TRUE the row points are outlined. Default TRUE.
Tcol if it is TRUE the column points are outlined. Default TRUE.
nclus labels for the clusters (default cl1, cl2, ...
cframe scale for graphics limits
ucal quality Representation Threshold in the plane. Default ucal=0
cex.global scale for the label sizes
infaxes place to put the axes information: "out","in","no". Default infaxes="out". If infaxes="out" the graphic is similar to FactoMineR graphics, otherwise the style is similar to the one in ade4, without axes information when infaxes="no"
cstar length of the rays between the centroids of the classes and their points

Details

It draws the factorial plane with the clusters. Only for objects FactoClass see FactoClass. The factorial plane is drawn with planfac and the classes are projected with s.class of ade4

Value

It draws the factorial plane x, y using $co, $li of the object of class FactoClass. If ucal > 0, the function inertia.dudi is used to calculate the quality of representation in the plane.
