Plot latent components of plsc or plslda.
# S3 method for plsc
plot(x, dimen, ...)# S3 method for plslda
plot(x, dimen, ...)
An object of class "trellis".
An object of class plsc or plslda.
The index of latent components to be used for the plot.
Further arguments. See corresponding entry in
xyplot for non-trivial details. One argument is
ep: an integer for plotting ellipse. 1 and 2 for
plotting overall and group ellipse, respectively. Otherwise, none.
For details, see panel.elli.1.

Two functions are methods for the generic function plot() of
class plsc and plslda.
If the length of dimen is greater than 2, a pairs plot is used.
If the length of dimen is equal to 2, a scatter plot is drawn.
Otherwise, the dot plot is drawn for the single component.

data(abr1)
cl <- factor(abr1$fact$class)
dat <- abr1$pos
mod.plsc <- plsc(dat,cl,ncomp=4)
mod.plslda <- plslda(dat,cl,ncomp=4)
## Second component versus first
plot(mod.plsc,dimen=c(1,2),main = "Training data", ep = 2)
plot(mod.plslda,dimen=c(1,2),main = "Training data", ep = 2)
## Pairwise scatterplots of several components
plot(mod.plsc, main = "Training data", ep = 1)
plot(mod.plslda, main = "Training data", ep = 1)
## single component
plot(mod.plsc,dimen=c(1),main = "Training data")
plot(mod.plslda,dimen=c(1),main = "Training data")
