hclust and heatmap - slightly different dendrograms?
...hclust(dist(t(x))), and realized that the two
dendrograms were slightly different, in that the left-right
arrangement of one pair of subclusters (columns) was reversed in the
two functions (but all individual columns were grouped correctly).
Looking through the code for heatmap as a most definite nonexpert, it
seems to me that hclust is also invoked by heatmap.
> heatmap
function (x, Rowv = NULL, Colv = if (symm) "Rowv" else NULL,
distfun = dist, hclustfun = hclust, add.expr, symm = FALSE,
...
hcr <- hclustfun(distfun(x))
ddr <- as.dendrogram(hcr)
....
hcc <-...

identical(0, -0)
I'll save space and not include previous messages.
My 2 cents: At the very least the documentation needs a fix. If it is
easy to do, then Ted Harding's suggestion of a switch (default OFF) to
check for sign difference would be sensible.
I would urge inclusion in the documentation of the +0, -0 example(s) if
there is NOT a way in R to distinguish these. There are occasions where

Protocol for answering basic questions
I have been following the discussions on 'Reasons not to answer very basic questions in a straightforward way' with interest as someone who is also new to R and has had similar experiences. As such it with sadness that I note that most seem to agree with the present approach to the responses to basic questions. I must thank those respondants to my own questions who have been helpful, but
