Hi everybody, I'm making an application using the package tcltk. Everything goes fine until I load the package RGtk. The interface doesn't work anymore. Is there any conflict between these packages? I thought about unloading the package RGtk but I don't know how to do that. Thanks, -- Talita Perciano Costa Leite Graduanda em Ci??ncia da Computa????o Universidade Federal de Alagoas

Hi people, I'm developing an application (in Linux) using tcltk and calling ggobi from that application (using the Rggobi package). After I load ggobi and want to use the windows made by tcltk I get some errors and sometimes R cracks. I believe the problem is because the packages Rggobi, RGtk and tcltk are running together. I thought about a solution that would be unload the Rggobi and RGtk

Do you know of any references that verify the accuracy of R for basic statistical calculations and tests. The results of these studies should indicate that R results are the same as the results of other statistical packages to a certain number of decimal places on some benchmark calculations.

Dear users, I'm generating some images in R to put into a document that I'm producing using Latex. This document in Latex is following a predefined model, which does not accept compilation with pdflatex, so I have to compile with latex -> dvi -> pdf. Because of that, I have to generate the images in R with postscript (I want a vector format to keep the quality). The problem is that

Dear R-Help members, I have a question about how to save to the hard drive the one thousand datasets I generated in a simulation. The datasets are created in a "for" loop that repeatedly creates normally distributed datasets, such as the example below: Library(MASS) for (number in 1:1000) { dataset = mvrnorm(n = 400, mu = c(0,0,0), Sigma =

Hello! I'm not sure if is it a BUG or not...
