Graphical representation of simultaneous analysis.

1 2	## S3 method for class 'SimAn' plot(x, s1 = 1, s2 = 2, screen = TRUE, oar = 1, oac = 1, ...)

`x`	The output of the simultaneous analysis (class 'SimAn')
`s1`	Dimension to plot on horizontal axis
`s2`	Dimension to plot on vertical axis
`screen`	TRUE (all the graphs on screen) or FALSE (graphs in a file) FALSE for S-plus
`oar`	Output for active rows (1 = yes, 0 = no)
`oac`	Output for active columns (1 = yes, 0 = no)
`...`	Further arguments passed to or from other methods

The parameters s1 = 1 and s2 = 2 (by default) indicate that the graph is given for the first two dimensions. A plot of e.g. the second and the third dimensions is obtained by setting s1 = 2 and s2 = 3. Notice that in the latter case nd, the dimensionality of the solution, must be at least 3.

A large number of elements can take part in the SA of a set of tables depending on the number of tables and on the dimensions of the tables. In order to facilitate interpretation, the plot.SimAn function gives several graphical outputs for active and supplementary points (if any) including the ones corresponding to the separate CA of each table.

Each table is identified with a different color and the columns and partial rows of each table are in the same color and have the same symbol. Two additional graphs, one for the projections of the tables and one for the relations between factors of CA and SA are also provided by plot.SimAn.
