Grouping clusters from dendrograms
...ouping data that overlap branches. However, I'm not
sure if this is because of the script I am using to visualise the data which
may be incorrect.
The script I tried was:
> dendro<-hclust(as.dist(combo2),method="average")
> cut2<-cutreeDynamicTree(dendro,maxTreeHeight=1,deepSplit=TRUE,minModuleSize=1)
I then used the following to visualise the data:
> cut2colour<-labels2colors(cut2)
> plotDendroAndColors(dendro,cut2colour,"Dynamic Tree Cut",
> dendroLabels=FALSE,hang=0.03,addGuide=TRUE,guideHang=0.05)
Any advice or ideas would be much appreciated!...

cutreeDynamic error
...nd = FALSE, type =

Then I clustered using DIANA
dd.diana<-diana(dd.daisy)
I am trying to cutreeDynamic {dynamicTreeCut} as follows
cutreeDynamic(dd.diana, cutHeight = 2, minClusterSize = 1, method =
"hybrid",+ distM = dd.daisy,+ deepSplit =
(ifelse(method=="hybrid", 1, FALSE)),+ maxCoreScatter =
NULL, minGap = NULL,+ maxAbsCoreScatter = NULL,
minAbsGap = NULL,+ maxDistToLabel = cutHeight,+
respectSmallClusters = TRUE, + verbose = 2, indent
= 0)
But get the following error:

Manually modifying an hclust dendrogram to remove singletons
Dear R-Help,
I have a clustering problem with hclust that I hope someone can help
me with. Consider the classic hclust example:
hc <- hclust(dist(USArrests), "ave")
plot(hc)
I would like to cut the tree up in such a way so as to avoid small
clusters, so that we get a minimum number of items in each cluster,
and therefore avoid singletons. e.g. in this example, you can see
