Mating preference of frogs
A matrix with 9 columns representing different mating calls, and 36 rows, representing the results of repeated pairwise preference tests.
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
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
NA columns $i$ and $j$, the its entries show the
number of times the frog preferred stimulus $i$ or stimulus
The first form may be converted to the second using function
as.pairwise(). Note that the square matrix may have
entries off the main diagonal (some pairs did not meet).
