The following plot types are provided: `"jointplot"`

plots row and column scores into the same device, `"rowplot"`

and `"colplot"`

plot the row scores and column scores, respectively, in separate devices. For these types of plots 3-dimensional versions are provided. The graph plot is an unlabeled version of the joint plot where the points are connected by lines. Options are provided (`wlines`

) to steer the line thickness indicating the connection strength.

The regression plot (`"regplot"`

) provides two plots.
First, the unscaled solution is plotted. A frequency grid for the row
categories (x-axis) and column categories (y-axis) is produced.
The regression line is based on the category weighted means of the relative frequencies:
the blue line on the column-wise means on the x-axis and the column category on the y-axis,
the red line is based on the row categories on the x-axis and the row-wise means on the y-axis.
In a second device the scaled solution is plotted. The frequency grid is determined by
the row scores (x-axis) and the column scores(y-axis).
Now, instead of the row/column categories, the column scores (black line y-axis)
and the row scores (red line x-axis) are used.

The transformation plot (`"transplot"`

) plots the row/column categories against the row/column scores. The Benzecri plot (`"benzplot"`

) plots the observed distances against the fitted distances. It is assumed that the CA result is Benzecri scaled. The ordination diagram (`"orddiag"`

) for CCA produces a joint plot and includes the column and row covariates based on intraset correlations.
