A wrapper which carries out HCA and plots a dendrogram colored by the
information in a Spectra
object. Many methods for computing
the clusters and distances are available.

spectra |
An object of S3 class |
c.method |
A character string describing the clustering method; must be
acceptable to |
d.method |
A character string describing the distance calculation
method; must be acceptable as a method in |
use.sym |
A logical; if true, use no color and use lower-case letters to indicate group membership. |
leg.loc |
Character; if |
... |
Other parameters to be passed to the plotting functions. |
A list, containing an object of class hclust
and an
object of class dendrogram
. The side effect is a plot.

hclust
for the underlying function.
hcaScores
for similar analysis of PCA scores from a
Spectra
object. plotHCA
for the function that
actually does the plotting.
