plot.dudi: Factorial Planes from Objects of Class dudi

Description

It plots factorial planes from objects of class dudi

Usage

# S3 method for 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)

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

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

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")
