1 2 3 |
list |
A list |
A symmetric matrix of dimension mxm
, where m
is the
length of the list
pairwiseOverlapDistance
is defined the pairwise overlap distance.
1 2 3 4 5 6 7 8 | myList <- list(first=LETTERS[3:5], second=LETTERS[1:3], third=LETTERS[1:5], fourth=LETTERS[6:10])
pairwiseOverlapCoefficient(myList)
pairwiseOverlapDistance(myList)
poormanPOC <- function(list) {
sapply(list, function(x) sapply(list, function(y) overlapCoefficient(x,y)))
}
stopifnot(identical(pairwiseOverlapCoefficient(myList), poormanPOC(myList)))
