Correlation or Distance Biplot

Use this to provide a biplot representation of the results from a canonical correspondence or redundancy analysis. A biplot axis is drawn from origin through the first (and second) explanatory variable, showing the direction of variation for that variable. Projections of the species (or site) scores onto that variable are then made.

Available data

This lists data structures appropriate to the current input field. It lists texts for use in specifying the labels for the individuals and/or the variables. Double-click a name to copy it to the current input field or type the name.

First explanatory variable

Specifies the explanatory variable used for the first biplot axis. If the variable is a variate, you can enter its identifier into the input field. Alternatively, you can set it to the position of the variable in the list of variables involved in the analysis.

Second explanatory variable

Specifies the explanatory variable used for the second biplot axis. If the variable is a variate, you can enter its identifier into the input field. Alternatively, you can set it to the position of the variable in the list of variables involved in the analysis.

X-dimension

Specifies the dimension to show in the x-axis.

Y-dimension

Specifies the dimension to show in the y-axis.

Type of plot

Lets you plots either the Species scores or Site scores.

Labels for explanatory variables

Can be used to specify what type of labels to use to identify the explanatory variables on the plot. Select Numbers to display the sequential numbering of the explanatory variables, None for no labels, Identifiers to display the identifier names, or Labels to supply alternative labels using the name of a text structure in the space provided.

Labels for species (or site) scores

Can be used to specify what type of labels to use to identify the species (or site) scores on the plot. Select Numbers to display the unit numbers, None for no labels, Identifiers to display the identifier name for the scores (species scores only), or Labels to supply alternative labels using the name of a text structure in the space provided.
