Plot state tables or transition graphs of attractors
Description
Visualizes attractors, either by drawing a table of the involved states in two colors, or by drawing a graph of transitions between the states of the attractor.

Details
This function comprises two different types of plots:
The "table" mode visualizes the gene values of the states in the attractor and is only suited for synchronous or steadystate attractors. Complex asynchronous attractors are omitted in this mode. Attractors in attractorInfo
are first grouped by length. Then, a figure is plotted to the currently selected device for each attractor length (i.e. one plot with all attractors consisting of 1 state, one plot with all attractors consisting of 2 states, etc.). If ask=TRUE
and the standard X11 output device is used, the user must confirm that the next plot for the next attractor size should be shown.
The figure is a table with the genes in the rows and the states of the attractors in the columns. Cells of the table are (by default) red for 0/OFF values and green for 1/ON values. If grouping
is set, the genes are rearranged according to the indices in the group, horizontal separation lines are plotted between the groups, and the group names are printed.
The "graph" mode visualizes the transitions between different states. It creates a graph in which the vertices are the states in the attractor and the edges are state transitions among these states. This mode can visualize all kinds of attractors, including complex/loose attractors. One plot is drawn for each attractor. As before, this means that on the standard output device, only the last plot is displayed unless you set par(mfrow=c(...))
accordingly.
Value
If mode="table"
, a list of matrices corresponding to the tables is returned. Each of these matrices has the genes in the rows and the states of the attractors in the columns.
If mode="graph"
, a list of objects of class igraph
is returned. Each of these objects describes the graph for one attractor.
