Permutation Test for cross-type nearest neighbor distances
cnnTest( dist, n1, n2, w = rep(1, n1 + n2), B = 999, alternative = "less", returnSample = TRUE, parallel = FALSE, ... )
dist |
a distance matrix, the upper n1 x n1 part contains distances between objects of type 1 the lower n2 x n2 part contains distances between objects of type 2 |
n1 |
numbers of objects of type 1 |
n2 |
numbers of objects of type 2 |
w |
(optional) weights of the objects (length n1+n2) |
B |
number of permutations to generate |
alternative |
alternative hypothesis ("less" to test H0:Colocalization ) |
returnSample |
return sampled null distribution |
parallel |
Logical. Should we use parallel computing? |
... |
additional arguments for mclapply |
a list with the p.value, the observed weighted mean of the cNN-distances, alternative and (if returnSample) the simulated null dist
