Dear Sir,

This is Ms. Setsuko Kinoshita writing from Japan.

I have a question about " missing value" in Hierarchical Clustering.
Hierarchical Clustering was not available the data with missing value for earlier version of "R".
I used Euclidean distance and complete linkage method for "plot(hclust(dist()),hang=-1)".

How are missing values treated for Hierarchical Clustering in the latest "R 1.7.1" program?
e.g. : Is an average replaced ?

Yours Sincerely,

Setsuko Kinoshita
