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 class '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

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)
