what is the definition of your similarity? For two variables, you can compare two mean values from two sample by t-test (t.test()) or rank test (such as wilcox.test()). You also can measure the similarity between two distribution by Euclidean or other distance (dist()) . The ks.test() and chisq.test() can be considered too. More than two, you must do some variance analysis.
I think the R basic package is enough. 2005/6/6, Navarre Sabine <[EMAIL PROTECTED]>: > > Hi, > > I would like to know the similarity between variables, but I don't exactly > how begin and as from what dataframe or matrix! > > I have a matrix where in row I have 'Good', 'Medium','Bad' and in columns > I have my Criterions ! > > What function and package should I use? > > Thanks a lot > > Sabine > > --------------------------------- > > ils, photos et vid�os ! > > [[alternative HTML version deleted]] > > ______________________________________________ > [email protected] mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide! > http://www.R-project.org/posting-guide.html > -- ADDRESS: Bioinformatics Center, Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences 320 Yueyang Road, Shanghai 200031, P.R.China TELEPHONE: 86-21-54920086 [[alternative HTML version deleted]] ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
