corAxis: Correlation between ordination axes

Description

Calculates the Pearson product-moment correlation coefficient for the site scores of ordination axes.

Usage

corAxis(x, ...)
# S3 method for default
corAxis(x, ...)
# S3 method for symcoca
corAxis(x, axes = NULL, ...)

Value

A named vector containing the correlation coefficients for the requested axes.

Arguments

x

an ordination object. Only methods for objects of class symcoca are currently available.

axes

numeric; the number of axes to calculate the correlation coefficients for. If NULL, coefficients for all axes are returned.

...

arguments to be passed on to other methods.

Examples

od <- options(digits = 4)
## load some data
data(beetles)
data(plants)

## log transform the beetle data
beetles <- log(beetles + 1)

## symmetric Co-CA model
beetles.sym <- coca(beetles ~ ., data = plants, method = "symmetric")

## correlations between axes
corAxis(beetles.sym)
options(od)
