Ordination Point Pair-Wise Distance Calculation
Calculates the pair-wise distances of all points in an ordination. The function is simply a wrapper for the ‘dist’ function, but simplifies managing ordinations that store their coordinates under different names, as well as managing the desired dimensionality of the calculations.
orddist(x,dim)
An object of class ‘dist’ is produced
Ordinations are low dimensional representations of multidimensional spaces. This function produces data on the low-dimensional distances for other analyses.
data(bryceveg) # produces a vegetation data.frame dis.bc <- dsvdis(bryceveg,'bray/curtis') # creates a Bray/Curtis #dissimilarity matrix pco.bc <- pco(dis.bc,2) # produces a two-dimensional Principal # Coordinates Ordination object orddist(pco.bc,dim=2)
