kplot.pta: Multiple Graphs for a Partial Triadic Analysis

Description

performs high level plots of a Partial Triadic Analysis, using an object of class pta.

Usage

# S3 method for pta
kplot(object, xax = 1, yax = 2, which.tab = 1:nrow(object$RV), 
    mfrow = NULL, which.graph = 1:4, clab = 1, cpoint = 2, csub = 2, 
    possub = "bottomright", ask = par("ask"), ...)

Arguments

object

an object of class pta

xax, yax

the numbers of the x-axis and the y-axis

which.tab

a numeric vector containing the numbers of the tables to analyse

mfrow

parameter of the array of figures to be drawn, otherwise the graphs associated to a table are drawn on the same row

which.graph

an option for drawing, an integer between 1 and 4. For each table of which.tab, are drawn :

1

the projections of the principal axes

2

the projections of the rows

3

the projections of the columns

4

the projections of the principal components onto the planes of the compromise

clab

a character size for the labels

cpoint

a character size for plotting the points, used with par("cex")*cpoint. If zero, no points are drawn.

csub

a character size for the sub-titles, used with par("cex")*csub

possub

a string of characters indicating the sub-title position ("topleft", "topright", "bottomleft", "bottomright")

ask

a logical value indicating if the graphs requires several arrays of figures

…

further arguments passed to or from other methods

Examples

# NOT RUN {
data(meaudret)
wit1 <- wca(dudi.pca(meaudret$spe, scan = FALSE, scal = FALSE), 
  meaudret$design$season, scan = FALSE)
kta1 <- ktab.within(wit1, colnames = rep(c("S1", "S2", "S3", "S4", "S5"), 4))
kta2 <- t(kta1)
pta1 <- pta(kta2, scann = FALSE)
kplot(pta1)
kplot(pta1, which.graph = 3)
