Dear All, Is there a emacs/xemacs for unix without compiling it? If it is possible, I prefer something that I can use immediately after putting it on the unix server. Is it possible or am I too stupid to ask this kind of question?

Hi, I have created a plot using filled.contour() and have the problem that one of the axis titles and an axis label are overlapping. I have tried changing par()$mgp (with, e.g. par(mgp=c(4,1,0)) ), but this just makes the title go off the screen. I can't work out how to make the plot take up less space in the window, so I can hopefully change mgp and sort the problem. Is changing mgp the only

At the suggestion of many people, I have installed emacs on my linux (Fedora 8.0) computer with the intention of using emacs as window interface to R (2.6.0). I have gone though the emacs tutorial and don't see any information about how I should use emacs to run R. Can anyone suggest a document that I might read? In the past I have used R on a Windows XP system and used the built-in windowing

Hi, I have a large amount of data that I would like to create a histogram of and plot and do things with in R. It is pretty much impossible to read the data into R, so I have written a program to bin the data and now have a list of counts in each bin. Is it possible to somehow import this into R and use hist(), so I can, for instance, plot the probability density? I have looked at the help page

Hi, This may be a stupid question, but how are the "std. error" values returned by lm() calculated? For example > summary(lm) Call: lm(formula = log10(moments[2, 1:10]) ~ log10(L_vals[1:10])) Residuals: Min 1Q Median 3Q Max -0.0052534 -0.0019473 0.0006785 0.0011740 0.0059541 Coefficients: Estimate Std. Error t value

Hi all, I'd like to compare species richness patterns of two groups with paired observations with an extra continuous fixed effect as a covariate. Normally I would use a standard general mixed effect model for such data, with one group variable and a continuous variable as fixed effects, plus a random effect for the paired observations. However, after making such a model with the lme

Dear users, I'm using rpart for classification trees, but my code isn't working when I try to use all the variables in my data frame. This data frame was created from a data frame with 1775 variables, but I choose only 13. arv13<-rpart(iv~.,data=gn,method="class",parms=list(split="information")) #Error: Error in `[.data.frame`(frame, predictors) : undefined

Right now, I am using SAS and S+/R. As a new year resolution, I am planning to learn a scripting language. from statisticians' point of view, which scripting language is worth to learn, perl, python, or any other recommendation? (Most likely, I will be learning it in windows.) Since I am not in research, I will prefer one widely used in industry and related to statistical work. if you

Dear R-users, I am having trouble constructing nxn matrices involving calculations& conditions based on other tables.

Dear Lister, plot() is using the data range as the default limits of yaxis. Is there any way I can change the limits? I just look at the help of plot() and par() and couldn't find answers.

Dear All, I finally have chance to have R install on our unix server. However, the system admin asked me if I prefer command-line or gui interface. I have experience with R on linux before but never use R on unix. Here are my questions that I need you guys help. 1) is there a good gui for R/unix like we do for windows and mac? 2) if the answer for 1) is yes, which one is better interms of
