[R] New to R, trying to use agnes, but can't load my ditance matrix

[Karen R. Khar]

Hi,

I'm mighty new to R. I'm using it on Windows. I'm trying to cluster using a
distance matrix I created from the data on my own and called it D10.dist. I
loaded the cluster package. Then tried the following command...

> agnes("E:D10.dist", diss = TRUE, metric = "euclidean", stand = FALSE,
> method = "average", par.method, keep.diss = n < 1000, keep.data = !diss)

And it responded...

Error in agnes("E:D10.dist", diss = TRUE, metric = "euclidean", stand =
FALSE,  : 
  x is not and cannot be converted to class dissimilarity

D10.dist has the following data...

D1	0
D2	0.608392	0
D3	0.497451	0.537662	0
D4	0.634548	0.393343	0.537426	0
D5	0.558785	0.543399	0.632221	0.726633	0
D6	0.659483	0.701778	0.741425	0.668624	0.655914	0
D7	0.603012	0.659173	0.571776	0.687599	0.383712	0.683948	0
D8	0.611919	0.665357	0.526453	0.715093	0.457496	0.698213	0.317039	0
D9	0.41501	0.652117	0.552011	0.68969	0.485988	0.702738	0.42819	0.442598	0
D10	0.376512	0.600607	0.517857	0.673515	0.530421	0.667736	0.537025	0.48062
0.240559	0

I would appreciate any suggestions. Please assume I know virtually nothing
about R.

Thanks,
Karen

PS I'll eventually be using ~10,000 "species" to cluster. I'll need to have
within and between cluster distance info and I'll want a plot colored by
cluster. I agnes the right R tool to use?
