I' m trying to compute weighted mean on different groups but it only returns NA. If I use the following data.frame truc: x y w 1 1 1 1 2 2 1 3 1 1 4 2 0 2 1 0 3 2 0 4 1 0 5 1 where x is a factor, and then use the command : tapply(truc$y,list(truc$x),wtd.mean, weights=truc$w) I just get NA. What's the problem ? What can I do ?

I wrote a "program" truc.r with emacs In emacs, I start the buffer R, then I eval the buffer truc.r (C-c C-b) All is correct and I have my results. But, when I return to Console R, and make: > source ("truc.r"), I obtain an error: Erreur dans source("truc.r") : invalid multibyte character in par...

...eta distribution of the first kind). It works perfectly for a single value, but I want to apply it to a vector of 22 000 values. I can use a loop for the calculation of each value but it runs very very slowly. So, what can I change ? Hers's the function : p <- c(1,1) y <- 1 z <- 1 truc <- function(y) {y^(p[1]-1)/(1+y)^(p[1]+p[2])} pbeta2 <- function(z,p) 1/beta(p[1],p[2])*integrate(truc,0,z)$value machin <- pbeta2(vector,p) just return a single value Thanks for your help

Dear Luke ! Thanh you for the lovely packages. I have used it, it woks fine for Linux, XP, but concerning about windows 7 - 64 bits. I have problem with function makeCluster(). with R 13.0 version. I wonder it may caused a update problem or ??? Do you have any hint ??? Best Truc

...o works great, but how can I append lines? This function allows me to append new sheets in the file, but I would also like to append new lines of data onto one of the sheets.

Hi: How do I find average across three columns such as weight1, weight2, weight3 (20 people, each person has three different measures)? They have NA's also. Thanks Tom, Univ of Pittsburgh, ttrut at yahoo.com

I've been playing around with llvm lately and I was wondering something about the bitcode instructions for basic arithmetic. Is there any plan to provide instructions that perform widening multiply, or add with carry? It might be written as: mulw i32 %lhs %rhs -> i64 ; widening multiply addw i32 %lhs %rhs -> i33 ; widening add addc i32 %lhs, i32 %rhs, i1 %c -> i33 ; add with carry...
