R devel - Apr 2004 - rect.hclust fails when k is specified (PR#6740)

Submission from: (NULL) (194.186.91.129)


V<-t(matrix(scan('C:/V3.dat'),3))
d<-dist(V)
hc<-hclust(d)
rect.hclust(hc,5)

Error message is displayed:

Read 24 items
Error in rect(m[which[n]] + 0.66, par("usr")[3], m[which[n] + 1] +
0.33,  :
        plot.new has not been called yet

Here's my data file ('C:/V3.dat')

-1	-73	12
-70	-26	-8
-78	-101	-35
-38	-24	-16
39	-54	3
-40	-13	-19
-45	-9	-19
-18	-22	2

I don't think that's a bug.  As ?rect.hclust says, it adds a rectangle
to
the dendrogram, which means you need to plot the dendrogram _first_.  See
the example code in the help file.
