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,gg=FALSE)

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
`gg`	If TRUE the version ggplot ggrepel is perfomance. Default FALSE

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

Examples

data(Bogota)
ca <- dudi.coa(Bogota[,2:7],scannf=FALSE,nf=2)
# ade4 style
plotfp(ca$li,eig=ca$eig,main="First Factorial Plane",infaxes="in")
# with ggplot2 and ggrepel
plotfp(ca$li,eig=ca$eig,main="First Factorial Plane",gg=TRUE)
