x/y coordinates of dendrogram branches
Dear R-users, I need some help concerning the plotting of dendrograms for hierarchical agglomerative clustering. The agglomeration niveau of each step should be displayed at the branches of the dendrogram. For this I need the x/y coordinates of the branch-agglomerations of the dendrogram. The y-values are known (the heights of the agglomeration), but how can I get the x-values? > mydata <- c(1,2,3,4,5) > hc...

non-uniqueness in cluster analysis
Hi, I'm clustering objects defined by categorical variables with a hierarchical algorithm - average linkage. My distance matrix (general dissimilarity coefficient) includes several distances with exactly the same values. As I see, a standard agglomerative procedure ignores this problems, simply selecting, above equal distances, the one that comes first. For this reason the analysis in output

Would it make sense for xray instrumentation be part of -fprofile-generate? PGO will affect inlining decisions etc for the optimized binary, but the collected traces during the instrumented build would still have quite a bit of useful information. -- Sean Silva On Mon, Jan 16, 2017 at 4:33 PM, Xinliang David Li <xinliangli at gmail.com> wrote: > Google GCC records profile data (dynamic

method default for hclust function
I could not figure out what was the default when I ran hclust() without specifying the method. For example: I just have a code like: hclust(dist(data)) Any input would be appreciated:) [[alternative HTML version deleted]]

That’s a very good point, the X-ray data that would be useful for the linker should be collected from a "profile-use” build to be accurate. IIUC, that’d look like: build with profile-gen -> run benchmarks -> build with profile-use + Xray -> run benchmarks -> build with profil-use and feed linker with X-ray data for layout optimization. — Mehdi > On Jan 16, 2017, at 8:25
