R help - May 2002 - hclust.identify problem

Having some problems with using hclust.identify on my data, I revert to trying 
it out on the example in the help manual.  My result is still the same (as with 
my own data):

data(iris)
hci <- hclust(dist(iris[,1:4]))
plot(hci)
testx<-identify.hclust(hci)
Error in rect.hclust(x, k = k, x = x$x, cluster = cluster[, k - 1], border 
= "red") : 
        k must be between 2 and 0
identify.hclust(hci, function(k) print(table(iris[k,5])))
Error in rect.hclust(x, k = k, x = x$x, cluster = cluster[, k - 1], border 
= "red") : 
        k must be between 2 and 0

Any suggestions?

I am using R : Copyright 2002, The R Development Core Team
Version 1.5.0  (2002-04-29)  The hclust package was also downloaded 
at the sametime I downloaded the base and other packages (circa May 10th or
so).

I am using the Windows binaries on a DELL laptop with 256 MB of ram running
Windows 2000.

The other stuff I have wanted to use in the hclust package seems to be working 
fine.

Best, Mark Hall

It's a bug in identify.hclust (sic).  `x' is used in two senses.
For the record, please send to R-bugs.
