plotRMSE.ipls: RMSE development plot

In mdatools: Multivariate Data Analysis for Chemometrics

RMSE development plot

Description

Shows how RMSE develops for each iteration of iPLS selection algorithm.

Usage

## S3 method for class 'ipls'
plotRMSE(
  obj,
  glob.ncomp = obj$gm$ncomp.selected,
  main = "RMSE development",
  xlab = "Iterations",
  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 RMSE values obtained at each iteration of the iPLS algorithm as bars. The first bar correspond to the global model with all variables included, second - to the model obtained at the first iteration and so on. Number at the bottom of each bar corresponds to the interval included or excluded at the particular iteration.
