Used with binary predicates to do spatial joins. It's more likely that these will return something like plyr::join_keys() than a matrix:
plyr::join_keys()
plyr::join.keys(data.frame(x = 1:5, y = 2), data.frame(x = 2:1), by = "x") #> $x #> [1] 1 2 3 4 5 #> #> $y #> [1] 2 1 #> #> $n #> [1] 5
Distance matrices can probably use the existing R infrastructure for distance.
