Compare two distance matrices
Hi all,
I am trying to compare two distance matrices with R. I would like to
create a XY plot of these matrices and do some linear regression on
it. But, I am a bit new to R, so i have a few questions (I searched in
the documentation with no success).
The first problem is loading a distance matrix into R. This matrix is
the output of a the Phylip program Protdist and lookes like this:

And then, I follow from help:
> pco1 = dudi.pco(dist1, nf=2, scannf=F)
> pco2 = dudi.pco(dist2, nf=2, scannf=F)
> coi = coinertia(pco1, pco2, nf=2, scannf=F)
> testco1 = randtest.coinertia(coi, nrepet=1000)
The result is:
> Error in randtest.coinertia(coi, nrepet = 1000) : Not yet available
Could anyone help with thi...
