ENmisc contains two utility function mtapply is a hybrid of mapply and tapply. It evaluates summary function for each cell of data defined by a fixed set of factor values. The reason I wrote it was to be able to compute weighted means (using wtd.mean from Hmisc) to groups of data defined by factors, but it accepts any multivariate function as the function argument
wtd.boxplot does what the name makes you expect, it computes and draws boxplots for weighted data. It behaves like boxplot, but accepts an additional argument, weights. _______________________________________________ R-packages mailing list r-packa...@r-project.org https://stat.ethz.ch/mailman/listinfo/r-packages ______________________________________________ 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.
