##### Details

Dataset frogs.matrix is a 9-by-9 matrix with rows and columns corresponding to 9 stimuli presented to a female frog. Entry $(i,j)$ corresponds to the number of times the frog preferred stimulus $i$.

Dataset frogs is a 36-by-9 matrix with each row corresponding to a pair of distinct stimuli [$36=9*(9-1)/2$]; if a row has non-NA columns $i$ and $j$, the its entries show the number of times the frog preferred stimulus $i$ or stimulus $j$.

The first form may be converted to the second using function as.pairwise(). Note that the square matrix may have NA entries off the main diagonal (some pairs did not meet).

See purum.Rd for another mating preference dataset.
