find clusters with relatively high/low
p-values. pvrect and lines (S3 method for class
pvclust) highlight such clusters in existing plot, and
pvpick returns a list of such clusters.
character string which specifies the p-value to be
used. It should be either of "au" or "bp",
corresponding to AU p-value or BP value, respectively. See
plot.pvclust for details.
type
one of "geq", "leq", "gt" or
"lt". If "geq" is specified, clusters with
p-value greater than or equals the threshold given by
"alpha" are returned or displayed. Likewise "leq"
stands for lower than or equals, "gt" for
greater than and "lt" for lower than the
threshold value. The default is "geq".
max.only
logical. If some of clusters with high/low
p-values have inclusion relation, only the largest cluster is
returned (or displayed) when max.only=TRUE.
border
numeric value which specifies the color of borders of
rectangles.
col
numeric value which specifies the color of lines.
lwd
numeric value which specifies the width of lines.
...
other graphic parameters to be used.
Value
pvpick returns a list which contains the following values.
clusters
a list of character string vectors. Each vector
corresponds to the names of objects in each cluster.
edges
numeric vector of edge numbers. The i'th element
(number) corresponds to the i'th name vector in
clusters.
