multiblock_plots: Plot Functions for Multiblock Objects

Description

Plotting procedures for multiblock objects.

Usage

# S3 method for multiblock
scoreplot(
  object,
  comps = 1:2,
  block = 0,
  labels,
  identify = FALSE,
  type = "p",
  xlab,
  ylab,
  main,
  ...
)
# S3 method for multiblock
loadingplot(
  object,
  comps = 1:2,
  block = 0,
  scatter = TRUE,
  labels,
  identify = FALSE,
  type,
  lty,
  lwd = NULL,
  pch,
  cex = NULL,
  col,
  legendpos,
  xlab,
  ylab,
  main,
  pretty.xlabels = TRUE,
  xlim,
  ...
)
loadingweightplot(object, main = "Loading weights", ...)
# S3 method for multiblock
biplot(
  x,
  block = 0,
  comps = 1:2,
  which = c("x", "y", "scores", "loadings"),
  var.axes = FALSE,
  xlabs,
  ylabs,
  main,
  ...
)

Arguments

object

multiblock object.

comps

integer vector giving components, within block, to plot.

block

integer/character for block selection.

labels

character indicating if "names" or "numbers" should be plot symbols (optional).

identify

logical for activating identify to interactively identify points.

type

character for selecting type of plot to make. Defaults to "p" (points) for scatter plots and "l" (lines) for line plots.

xlab

character text for x labels.

ylab

character text for y labels.

main

character text for main header.

...

Not implemented.

scatter

logical indicating if a scatterplot of loadings should be made (default = TRUE).

lty

Vector of line type specifications (see par for details).

lwd

numeric vector of line width specifications.

pch

Vector of point specifications (see points for details).

cex

numeric vector of plot size expansions (see par for details).

col

integer vector of symbol/line colours (see par for details).

legendpos

character indicating legend position (if scatter is FALSE), e.g. legendpos = "topright".

pretty.xlabels

logical indicating if xlabels should be more nicely plotted (default = TRUE).

xlim

numeric vector of length two, with the x limits of the plot (optional).

x

multiblock object.

which

character for selecting type of biplot ("x" = default, "y", "scores", "loadings").

var.axes

logical indicating if second axes of a biplot should have arrows.

xlabs

character vector for labelling first set of biplot points (optional).

ylabs

character vector for labelling second set of biplot points (optional).

Value

These plotting routines only generate plots and return no values.

Details

Plot functions for scores, loadings and loading.weights based on the functions found in the pls package.

Examples

# NOT RUN {
data(wine)
sc <- sca(wine[c('Smell at rest', 'View', 'Smell after shaking')], ncomp = 4)
plot(loadings(sc, block = 1), labels = "names", scatter = TRUE)

# }
