Make Ordination Axis Labels

Description

Makes ordination axis labels that include, if appropriate, the % total variance explained by each axis.

Usage

ord_labels(ord)

Arguments

ord

A vegan ordination object.

Details

If there are no eigenvalues in ord, or if any eigenvalues are less than 0, each element of the vector returned has the form "DIMn" where n is the axis number. Otherwise, each element of the vector returned has the form "AxisN xx.x%" where "Axis" is taken from the vector of eigenvalues in ord if they are named or simply "DIM" if they are not, N is the number of the axis, and xx.x is the % of total variance explained by the axis.

Value

A character vector, each element of which can be used to label the corresponding axis of an ordination plot.

Examples

data("dune")
data("dune.env")
dune_hel <- decostand(dune, method = "hellinger")
ord <- rda(dune_hel)
axis_labels <- ord_labels(ord)
axis_labels[c(1,2)]
