Dear R users, Due to too many children in my clustering result, I would like to prune the tree-like hclust object into a certain groups. However, an error: > clip.clust: no data provided for hclust object always shows up. Firstly, I tried the example in the maptree package, and it worked well. Then, I tried to used the example in stats package to generate a hclust object and tried the clip.clust method again, and the error still occurred. Here is the example: > hc <- hclust(dist(USArrests), "ave") > pr <- clip.clust(hc, k=4) Error in clip.clust(hc, k = 4) : clip.clust: no data provided for hclust object
Have you read ?clip.clust ?? It says for argument "data": data clustered dataset for hclust application. whic means you need to provide "data" as the error message suggests as well. pr <- clip.clust(hc, k=4, data=USArrests) pr$membership works for me. Uwe Ligges
Does anyone have the idea? My environment is R version 2.10.1 (2009-12-14) x86_64-pc-linux-gnu [1] maptree_1.4-6 Best regards, Keith ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
