search for: dendrogam

I would like to explore dendrogam plots interactively. For example, click on a node and return information about all of the children of that node. Is there a high level wrapper for locator() or click() that will return the nearest dendrogram node on a plot? If not, is there a way to obtain the [x,y] coordinates of all the nodes...

...; result$membership <- membership > dend <- as.dendrogram(result) where merges is as above, and membership is: > membership [1] 0 0 0 0 0 2 2 2 2 2 1 1 1 1 1 Any thoughts on how to convert a dendrogram object to an hclust or phylo object, or barring that, another way to plot a radial dendrogam in R?

...am(gclus),Colv=as.dendrogram(sclus),col=rbg) Johan> Error in match.fun(FUN) : evaluation is Johan> nested too deeply: infinite recursion? Error: Johan> evaluation is nested too deeply: infinite recursion? The problem happens when trying to plot a large dendrogram. The "dendrogam" class is implemented as an S-level "tree", i.e., a nested list and plot.dendrogram() uses recursion for plotting. To avoid infinite recursion (which would typically "freeze" your computer), there's a limit in R (and S), options(expressions = 500) for how deeply...

Hello, When trying to run mvpart either specifying my own parameters or using the defaults, I get the following error: Error in all(is.leaf) : unused argument(s) (c(FALSE, TRUE, FALSE, FALSE, TRUE, TRUE, TRUE)) As far as I can tell, is.leaf is part of the dendrogam package, so I'm assuming there's some problem with the graphical parameters. However running same formula and data through rpart yields no errors, and I don't remember seeing this when I ran the same data through mvpart a couple years ago. Any suggestions as to where a solution might li...

...port for conditionals in NAMESPACE files. o Added as.list.environment to coerce environments to lists (efficiently). o New function addmargins() in the stats package to add marginal summaries to tables, e.g. row and column totals. (Based on a contribution by Bendix Carstensen.) o dendrogam edge and node labels can now be expressions (to be plotted via stats:::plotNode called from plot.dendrogram). The diamond frames around edge labels are more nicely scaled horizontally. o Methods defined in the methods package can now include default expressions for arguments. If these arg...
