R: Factorial Planes from Coordinates

plotfp

R Documentation

Factorial Planes from Coordinates

Description

It plots factorial planes from a coordinate table

Usage

plotfp(co,x=1,y=2,eig=NULL,cal=NULL,ucal=0,xlim=NULL,ylim=NULL,main=NULL,
                   rotx=FALSE,roty=FALSE,eti=row.names(co),
                        axislabel=TRUE,col.row="black",cex=0.8,cex.row=0.8,
                        all.point=TRUE,cframe=1.2,cex.global=1,infaxes="out",asp=1)

Arguments

`co`	matrix or data.frame with coordinates
`x`	the component like horizontal axis
`y`	the component like vertical axis
`eig`	numeric with the eigenvalues
`cal`	matrix or data.frame with the square cosinus
`ucal`	quality representation threshold (percentage) in the plane . Default ucal=0
`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
`eti`	selected row 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"
`cex`	global scale for the labels. Default cex=0.8
`cex.row`	scale for row points and row labels. Default cex.row=0.8
`all.point`	If if is TRUE, all points are outlined. Default all.point=TRUE
`cframe`	scale for graphic limits
`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"
`asp`	the y/x aspect ratio

Details

Plot the selected factorial plane.

Value

It graphs the factorial plane x,y using co and optional information of eigenvalues and representation quality of the points. If ucal > 0, only the points with the quality of representation on the plane bigger than ucal are pointed
