Doubts about chi-square distribution
Dear list, For educational purposes I have been working with the script below. I have a observation: line 31 #CScal[i] = (amo^2) # IT IS WRONG, I KNOW, BUT IT MAKE R TO CRASHES! I'm thinking this is a possible bug in the R! And I have a couple of doubts: 1) line 51 #curve(dchisq(x, n-1), add = T, col = 'red' I think that it is correct, but the function no

Doubt about Student t distribution simulation
Dear R list, I would like to illustrate the origin of the Student t distribution using R. So, if (sample.mean - pop.mean) / standard.error(sample.mean) has t distribution with (sample.size - 1) degree free, what is wrong with the simulation below? I think that the theoretical curve should agree with the relative frequencies of the t values calculated: #== begin options===== # parameters

biplot package
Dears, I've been learning biplot (Gabriel, 1971) and I found the function 'biplot', inside of the package 'stats', useful but, a bit limited. So, I'm thinking to start a colaborative package to enhance this methods to other multivariate methods. In this way, I would like to start it, making public a new function (biplot.pca, still in development, but running) that make

A couple of suggestions: source function (package base)
Hi, I've been calling the function "source" (package base) from Tinn-R editor to send files, marked blocks and selections to R interpreter because it avoids a lot of problems related with input/output synchronization in the Rgui output! The new RGedit plugin is also using this function in this way, and we are finishing a new version of a plugin to Vim (Vim-R-plugin2) which uses
