From: Elio Mineo Thanks, Peter. So, in R 2.1.0 there is no way to get names from a "dist" object, isn't there?
If you are referring to the row names of the matrix from which distances are computed, see the "Value" section of ?dist, which has: The object has the following attributes (besides "class" equal to "dist"): Size integer, the number of observations in the dataset. Labels optionally, contains the labels, if any, of the observations of the dataset. [...] Andy

Linux Mandrake 10.0 (R compiled from source code). Is this a bug or not?
Not.
From the NEWS file:
o The S3 methods for getting and setting names of
"dist" objects
have been removed (as they provided names with a different
length from the "dist" object itself).
(some side effects are fixed in 2.1.0-patched)
