Dear R helpers! Is there an utility for multiple logistic regression where the response is not ordinal? As the predictors do not satisfy the necessary hypothesis, I cannot use discriminant analysis. Thanks and have a nice R-day Anne [[alternative HTML version deleted]]

Hello R-helpers I want to put a color scale in a plot: I've got an xy plot where the values of the response (z=f(x,y)) is symbolically given by colors (like heat or rainbow color scale) I would like to put such a scale with apprpriates labels in the plot, so as to facilitate the interpretation (like in a finite elements result plot) How is taht possible? Thanks Anne [[alternative

Hello! After a presentation of some statistical analysis of process datas, (where the few R possibilities I was able to show made quite a big impression), I was asked if it was possible to program a statistical application which could be used directly by the end user. Such an application would include a userfriendly interface (developped in C++), a db , a core statistical program, standard
