plot.residLen: Plot method for residual lengths

Description

Base graphics plot method for residLen objects.

Usage

# S3 method for residLen
plot(x, probs = c(0.9, 0.95, 0.99), ncol = 1,
     lcol = "red", llty = "dashed", xlab = NULL, ylab = NULL,
     main = "Residual distances", rug = TRUE, ...)

Value

A plot on the current device.

Returns, invisibly, a list with two components (train and

passive), each and object of the type returned by

density.

Arguments

x: Object of class "residLen", the result of a call to residLen.
probs: numeric; vector of probability quantiles to compute from the sets of residual distances.
ncol: numeric; number of columns for the plot layout. Choices are 1 or 2. Determines whether the histograms are plotted above or beside each other.
lcol, llty: colour and line-type for the quantiles.
xlab, ylab: Axis labels. If not supplied, suitable defaults are generated, depending on whether RDA or CCA was used as the underlying ordination model.
main: character; title for the plot.
rug: logical; should rug plots of the actual distances be drawn?
...: additional arguments passed to plot.

Examples

Run this code

## load the Imbrie and Kipp example data
data(ImbrieKipp, SumSST, V12.122)

## squared residual lengths for Core V12.122
rlens <- residLen(ImbrieKipp, SumSST, V12.122)
rlens

## plot a histogram of the residual distances
plot(rlens)
