plotSelection.ipls: iPLS performance plot

In mdatools: Multivariate Data Analysis for Chemometrics

iPLS performance plot

Description

Shows PLS performance for each selected or excluded intervals at the first iteration.

Usage

## S3 method for class 'ipls'
plotSelection(
  obj,
  glob.ncomp = obj$gm$ncomp.selected,
  main = "iPLS results",
  xlab = obj$xaxis.name,
  ylab = if (is.null(obj$cv)) "RMSEP" else "RMSECV",
  xlim = NULL,
  ylim = NULL,
  ...
)

Arguments

obj	iPLS results (object of class ipls).
glob.ncomp	number of components for global PLS model with all intervals.
main	main title for the plot.
xlab	label for x-axis.
ylab	label for y-axis.
xlim	limits for x-axis.
ylim	limits for y-axis.
...	other arguments.

Details

The plot shows intervals as bars, which height corresponds to RMSECV obtained when particular interval was selected (forward) or excluded (backward) from a model at the first iteration. The intervals found optimal after backward/forward iPLS selection are shown with green color while the other intervals are gray.

See examples in help for ipls function.
