plot.dudi: Factorial Planes from Objects of Class dudi

In FactoClass: Combination of Factorial Methods and Cluster Analysis

Factorial Planes from Objects of Class dudi

Description

It plots factorial planes from objects of class dudi

Usage

## S3 method for class 'dudi'
plot(x,ex=1,ey=2,xlim=NULL,ylim=NULL,main=NULL,rotx=FALSE,
      roty=FALSE,roweti=row.names(dudi$li),
      coleti=row.names(dudi$co),axislabel=TRUE,font.col="plain",
      font.row="plain",col.row="black",col.col="blue",
      alpha.col=1,alpha.row=1,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",gg=FALSE,...)
sutil.grid(cgrid,scale=TRUE)    

Arguments

x	object of type dudi
ex	number indentifying the factor to be used as horizontal axis. Default 1
ey	number indentifying the factor to be used as vertical axis. Default 2
xlim	the x limits (x1, x2) of the plot
ylim	the y limits of the plot
main	graphic title
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
font.row	type of font for row labels. Default "plain"
font.col	type of font for column labels. Default "plain"
axislabel	if it is TRUE the axis information is written
col.row	color for row points and row labels. Default "black"
col.col	color for column points and column labels. Default "blue"
alpha.row	transparency for row points and row labels. Default cex.ilu=1
alpha.col	transparency for column points and column labels. Default cex.ilu=1
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
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
cframe	scale for graphic limits
ucal	quality representation threshold (percentage) 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"
gg	If TRUE the version ggplot ggrepel is perfomance. Default FALSE
...	further arguments passed to or from other methods
cgrid	internal parameter
scale	internal

Details

Plot the selected factorial plane. sutil.grid is used by plot.dudi

Value

It graphs the factorial plane x,y using $co, $li of a "dudi" object. If ucal > 0, the function inertia.dudi is used to calculate the quality of representation on the plane

Examples

data(Bogota)
ca <- dudi.coa(Bogota[,2:7],scannf=FALSE,nf=4)
# with ggplot2 and ggrepel
plot(ca,gg=TRUE)
dev.new()
# ade4 style
plot.dudi(ca,ex=3,ey=4,ucal=0.2,all.point=FALSE,infaxes="in")
