[R] Cluster analysis with missing data

[Bill.Venables at csiro.au]

vegdist() in the vegan package optionally allows pairwise deletion of missing values when computing dissimilarities.  The result can be used as the first agrument to hclust()

('Caveat emptor', of course.)

Subject: [R]  Cluster analysis with missing data

Hi folks,

I tried for the first time hclust. Unfortunately, with missing data in my
data file, it doesn't seem
to work. I found no information about how to consider missing data.

Omission of all missings is not really an option as I would loose to many
cases.

Thanks in advance
Holger
