Re: [R] randomisation for matrix

Hi Knut, I think you're going to have to be more specific. The code matrix(rnorm(25), 5, 5) generates a random 5 by 5 matrix. If you need specific distributions, search through the helpfiles using help.search or RSiteSearch. --Gray On Wed, Jul 28, 2010 at 7:51 AM, Knut Krueger wrote: > Hi

Hi Marc, Thanks for the info on recovery - most of it can pieced together from backups but a quick, cheap and easy method of recovery would have been nicer. My main concern is that this could happen again and that the "bug" is not limited to R 2.9. I would think that an accidental carriag

Re: [R] memory problem for scatterplot using ggplot

It was my understanding that R wasn't really the best thing for absolutely huge datasets. 17.5 million points would probably fall under the category of "absolutely huge." I'm on a little netbook right now (atom/R32) and it failed, but I'll try it on my macbookPro/R64 later and see if it's able to

Re: [R] T and F (was: Optimization problem with nonlinear constraint)

Hi Patrick, Actually, I feel just the opposite, i.e. it is not a good idea to use `T' for `TRUE'. I have been snared by this trap many a times in my early days with S-Plus and R. It is a good practice to use unabbreviated values. Best, Ravi. -Original Message- From: r-help-boun...@r-

Re: [R] Glm

Ana, It's not really clear what you are trying to do. From your description, you aren't estimating anything. The code a <- c(1, 0.6, 0.8) x <- rnorm(2) y <- crossprod(c(1, x), a) generates 'y'; but nothing is estimated. 'y' is going to have the same variance regardless of how many observatio

Re: [R] Odp: Data frame modification

Hi why do you insist on loops. R is not C. If you want to use loops use C or similar programming languages. It is almost always better to apply whole object approach. Kind and clever people already programmed it (sometimes in C ). x<-rnorm(20) x[c(10,12,13,17)]<-NA x [1] -1.12423790 0.80641
