Dear R users, Is there the possibitily in R under X11 to get (after typing help(...) command) separate help window, as it is in Windows version?

Hi, I am still new to R and have a programming question. I have created a small function which takes a parameter. In the function I want to be able to refer to the names of the variables sent to the function (specifically I want to be able to use the name of the variable given to the function in an output table). For example, in the following (fictional) function I want some way of printing

Dear list, sorry to waste your time. I downloaded R and I like it very much. However, my main interest is in plotting 3D graphics form imported data (points and lines in a 3d space). I imported data in a very elegant way but I wasn't able to find in R something similar to the simple "splot" function of WGNUplot (I don't need persp, image, contour: my values are not

Hi, I need to plot the beta as the symbol, followed by the index 3 as the title of a graph. This code works> main= bquote(paste("Results for ", beta ==.(b1)) but I also need the index 3. I tried (simplified): >plot(x,y, main= bquote(paste("Results for ", beta, "3", ==.(b1)))) and a few other versions, but I can not get it to run properly. Any help would

Hi, I have a simple question. I have a variable with 3 levels. Variable A A A A A A B B B B B B C C C C C C I need to make a new vector renaming de levels B and C for D.

I also agree with Philippe Grosjean that there is a need to investigate the effects of different types of GUIs on software "usability". To do that, however, there is a need to develop a set of appropriate metrics, and to understand that the appropriateness of a given metric (and ultimately a given type of GUI) is likely to be conditional on the type of user. My sense is that the

Hi, Have you seen the tcltk package? I believe it is a better option than the one you outline in your message. Why develop a Windows-only GUI? Maybe in a few years your teaching department will give up Windows for Linux (for the reasons you wrote about R: it is free, advanced, and adaptable). There is an article in R News (vol.1, n?3) by Peter Dalgaard on the tcltk package, and the latter

Hi the list. I do not understand the philosophy behind numeric and integer. - 1 is numeric (which I find surprising) - 2 is numeric. - 1:2 is integer. Why is that ? Christophe
