[R] about mix type clust algorithm

2013-07-21 Thread Cheng, Yi
Hi: I have tried to find the appropriate clust algorithm for mixed type of data. The suggested way I see is: 1. use daisy to get the dissimilarity matrix 2. use PAM/hclust by providing the dissimilarity matrix, to get the clusters but by following this, when the data set grows bigger

Hi everyone, I am new to R , I have some doubts about RHadoop. Can the classification algorithms or data mining algorithms be used in the Rhadoop as well as it used in R? If so, are there some different usages in the achitecture of code? Are there some reference books or website listed some exampl

Re: [R] Different x-axis scales using c() in latticeExtra

2013-07-21 Thread Jeff Stevens
Thanks, David. The warnings occur after the true problem of trying to plot the three graphs with different scales. I should have stopped the example after assigning all_plots <- c(...), then plotted it (and left out the update statements). If you do this, the x-axes do not maintain their scales.

Many thanks, Felix. Though, it seems like the x.same option should allow this: "if TRUE, set the x scale relation to "same" and recalculate panel limits using data from all panels. Otherwise, the x scales in each panel will be as they were in the original objects (so in general not the same), the

Dear list, Just wonder if there is a limit on the number of code line in .Rhistory. When I check the .Rhistory, some code I enter at earlier time disappeared. If there is limit, how do I change it? Thanks. Jun [[alternative HTML version deleted]]
