Folks, I put up a brief note describing my naive attempts to compute Goldbach partitions, starting with a brute-force approach and refining progressively. http://jostamon.blogspot.com/2009/02/goldbachs-comet.html I'd welcome your suggestions on improvements, alternatives, other optimisations, esp. to do with space vs time tradeoffs. Is this an example interesting enough for

Hi, Can anyone guide me as to how I can add points to a p3d() plot from the onion package?? I want to plot points with different colors on the same 3D plot.? Perhaps I can do this without adding points but somehow directing the 'h' parameter to give different color to points based on a factor I assign to them? FYI, I can do this using using scatterplot3d() and points3d(), but these plots

Dear R-user I need a function to approximate a complex integration. My function is: aprox2=function(s,x,rate){ dexp(x,rate)*exp(-s*x) } where argument s is a complex number. I can't use the integrate function because it's only used with "numeric" arguments Does anyone know some function to approximate complex integrals? Thanks Borja [[alternative HTML version deleted]]

I'm looking for some tutorial on S4. I only find the following one, which is not in English. Can somebody let me know if there is any introductory material? I'm very familiar with OO and C++. If there is some material that suits my background, it will be great. https://stat.ethz.ch/pipermail/r-help/2009-January/184108.html

Hello everyone, Can someone tell me exactly how to generate data from a null distribution for the fisher exact test? I know I have to use the hypergrometric but exactly what commands do I use? Jim [[alternative HTML version deleted]]

Hi there I know, I'm sure you discussed this stuff 100 times, but I really have a basic understanding problem, if and how do I create a multidimensional array in R. I'm coming from MATLAB and there it's as easy as you ever could imagine. Ok, so, I want to have an array, where I can fill in data from a Excel spreadsheet. The array should be addressed like this:
