Neighbors

Calculates the nearest neighbors in a distance/dissimilarity matrix

neighbors(dis,numnbr)

`dis`	an object of class ‘dist’ such as returned by `dist`, `vegdist` or `dsvdis`
`numnbr`	the number (order) of neighbors to return

For each sample unit in a dissimilarity matrix finds the ‘numnbr’ nearest neighbors and returns them in order.

Returns a data.frame with sample units as rows and neighbors as columns, listed in order of proximity to the sample unit.

data(bryceveg) # returns a data.frame called veg
dis.bc <- dsvdis(bryceveg,'bray/curtis')
neighbors(dis.bc,5)
