Re: [R] newbie question on snow/Rmpi

Thanks, Dirk. I had read your very long conversation on the openMPI list but wasn't sure if there was a resolution. I had overlooked the fact that there is an hpc list, will post there from now on. Cheers, Whit On Fri, Dec 19, 2008 at 11:52 AM, Dirk Eddelbuettel e...@debian.org wrote: Whit,

[R] newbie question on snow/Rmpi

I have a network of four machines set up. I'm having trouble spawning my slaves on these machines. All the examples I have found so far use makeCluster with type=MPI, and I guess I'm missing some kind of cluster configuration in my environment variables because all my clusters are formed on the

Hello list, I just started R today and tried something quite simple. I wanted to create a colored plot and eventually after hours of fiddling around got it working. However, my solution seems very suboptimal and I'd really appreciate your hints on how to improve. I believe that R already offers

Re: [R] R Newbie Question

tIs a bit neater to create list objects for each of star1 and star2 and then, since the various functions are not used outside of gravitation stick them right in gravitation. Also we can use distance for len as well by giving it a default second arg of 0 and sqr does not seem to do much so we can

Re: [R] Newbie question: How to use tapply() on several vectors simultaneously

one option is aggregate(), e.g., test - as.data.frame(cbind(c(rep(1,5),rep(2,5)), rnorm(10), rnorm(10))) names(test)[1] - groupID aggregate(test[c(V2, V3)], list(test$groupID), mean) I hope it helps. Best, Dimitris -- Dimitris Rizopoulos Biostatistical Centre School of Public Health Catholic
