[R] accessing the "address" of items in a recursive list

Dear useRs, I am working on a project involving the clustering of a large dataset. I need to extract specific sub-clusters from the parent dendrogram for further analysis. The data is too large for the use of convenient tools such as identify.clust (it selects the specific group of interest o

[R] distance matrix to coordinate format for spatial stats

Greetings, I would like to use some of the spatial statistics functions in R, but I am having trouble entering data. My data is already in a distance matrix format, not an X Y coordinate format (each Xij cell in the matrix represens the distance from point i to j). Does anyone know of a way

[R] accessing nodes in a dendrogram

Hi All, I am new to R, so please excuse the simplicity of the question. I am trying to remove nodes from a dendrogram - specifically nodes that have less than 3 members. I am trying to create a function to do so, but I am not sure how to reference the node inside of the function. Here is the

[R] Removing dendrogram nodes with < 2 members

Greetings, I have a large dendrogram that I would like to use to extract groups. But any group with 2 or fewer members is not useful to me, so I would like to remove all of the nodes with less than 3 members from the dendrogram. 1) Is there a good way to iterate through a dendrogram list to ch

[R] creating large graphs

Dear useRs, I have a large dataset (600 to 2000 observations) that I need to cluster with a hierarchical technique, and then examine so that I can use cutree to extract various groups. I would like to visualize the results of hclust in a dendrogram, but this is obviously too much data for the

[R] exporting text output to pdf

Hello, I am new to R and I am trying to figure out how to print text output from an operation like table() to a pdf file. Is there a simple command to do this, or do you need to work with connections at a rudimentary level? Thanks you, Jesse [[alternative HTML version deleted]] ___
