plotXResiduals.pls: Residual distance plot for decomposition of X data

In mdatools: Multivariate Data Analysis for Chemometrics

Residual distance plot for decomposition of X data

Description

Shows a plot with orthogonal distance vs score distance for PLS decomposition of X data.

Usage

## S3 method for class 'pls'
plotXResiduals(
  obj,
  ncomp = obj$ncomp.selected,
  norm = TRUE,
  log = FALSE,
  main = sprintf("X-distances (ncomp = %d)", ncomp),
  cgroup = NULL,
  xlim = NULL,
  ylim = NULL,
  show.limits = c(TRUE, TRUE),
  lim.col = c("darkgray", "darkgray"),
  lim.lwd = c(1, 1),
  lim.lty = c(2, 3),
  show.legend = TRUE,
  legend.position = "topright",
  res = obj$res,
  ...
)

Arguments

obj	a PLS model (object of class pls)
ncomp	how many components to use (by default optimal value selected for the model will be used)
norm	logical, normalize distance values or not (see details)
log	logical, apply log tranformation to the distances or not (see details)
main	title for the plot
cgroup	color grouping of plot points (works only if one result object is available)
xlim	limits for x-axis
ylim	limits for y-axis
show.limits	vector with two logical values defining if limits for extreme and/or outliers must be shown
lim.col	vector with two values - line color for extreme and outlier limits
lim.lwd	vector with two values - line width for extreme and outlier limits
lim.lty	vector with two values - line type for extreme and outlier limits
show.legend	logical, show or not a legend on the plot (needed if several result objects are available)
legend.position	position of legend (if shown)
res	list with result objects to show the plot for (by defaul, model results are used)
...	other plot parameters (see mdaplotg for details)

Details

The function is almost identical to plotResiduals.pca.
