hist.residLen: Histogram plot for residual lengths

Description

Base graphics histogram plot method for residLen objects.

Usage

## S3 method for class 'residLen':
hist(x, breaks = "Sturges", freq = TRUE,
     probs = c(0.9, 0.95, 0.99), ncol = 1, lcol = "red",
     llty = "dashed", xlab = NULL, ylab = NULL,
     main = "Residual distances", rug = TRUE, ...)

Arguments

x

Object of class "residLen", the result of a call to residLen.

breaks

How breakpoints for the histogram are determined. See hist for more details.

freq

logical; if TRUE, the histogram graphic is a representation of frequencies, the counts component of the result; if FALSE, probability densities, component density, are plotted (so that the hi

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 hist.

Value

• A plot on the current device. Returns a list with two components (train and passive), each of which is an object returned by hist.
