R: Factorial Planes from Objects of Class dudi

plot.dudi

R Documentation

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,col.row="black",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",...)
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
`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"
`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"
`...`	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(ardeche)
ca <- dudi.coa(ardeche$tab,scannf=FALSE,nf=4)
# FactoMineR style
plot.dudi(ca,ucal=40,all.point=FALSE,main="SCA of Ardeche, First Factorial Plane")
dev.new()
# ade4 style
plot.dudi(ca,ex=3,ey=4,ucal=20,all.point=FALSE,infaxes="in",main="SCA of
Ardeche, Plane 3-4")
