The BigBang object can save information about solutions that did not reach the goalFitness. filter=="solutions" ensures that only chromosomes that reach the goalFitness are considered. fitlter=="none" take all chromosomes. filter=="nosolutions" consider only no-solutions (for comparative purposes).
subset
Second level of filter. subset can be a vector specifying which filtered chromosomes are used. It can be a logical vector or a numeric vector (indexes in order given by $bestChromosomes in BigBang object variable). If it is a numeric vector length one, a positive value means take those top chromosomes sorted by fitness, a negative value take those at bottom.
mord
The number of ``top-ranked-genes'' to highlight.
inc.rank
Incluye the gene rank in rownames and colnames.
inc.index
Incluye the gene index in rownames and colnames.
Value
Returns a matrix with number of overlaps for every top-ranked-gene pairs. The order correspond to rank.
