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 parser at line 1 If I copy, line by line the instructions of the

I have defined a function to compute the value of a beta distribution of the second kind (the existing beta distribution of th stats package is the beta 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

Dear list, I was trying to use the "notify" action with dovecot sieve but I just couldn't get it work. The relevant lines look as follows: ,-------- |require ["fileinto", "notyfy"]; | if header :contains ["to", "cc"] ["userA at example.com", "userB at example.com"] { | notify | :method "mailto" |

Dear R users, I've learned today about RODBC package in order to import xls file to dataframes and export the dataframes to xls files. However I have some problems. Please excuse me if these are basic but as I said, I've just begun with this package. Also this email is quite long, but everything is related, so I don't think it would be better to split it. Moreover, there's a

Dear R developers, I had some problem when building package: for exemple when building the package e1071 available from CRAN, I get the following message error: * checking for file 'e1071/DESCRIPTION' ...

Dear all Wine-users, I'm last-year student of Hanoi University of Technology in Vietnam. My graduate thesis has important part relate to Wine and installation of Windows applications in Linux via Wine. I have completed all part of my thesis except Wine related part. I installed Office XP with Wine May 2005 and it always failed. Before installed Office, I had installed Dcom98.exe ,

'sodexquan' is an data frame of numeric variables with some missing values. I would like to approximate these missing values using some algorithm. I thereby chose the mix package. But when trying to run the 'prelim.mix' function (aka the function that will prepare the data for further calculations), R says: prelim.mix(truc,0) Error in as.integer.default(list(c(32, 52, 32, 27, 34,

Hi Philip, Thanks for the response.

Hi, I'm new to ScalarEvolution and wanted to explore its capabilities. I have following few questions: 1) How to compare SCEV expressions. I have a situation to compare two SCEV to find the min among them. Found an existing function(getMinFromExprs) in LoopAccessAnalysis which compares two SCEVs. getMinFromExprs function finds the diff between two SCEV's and then checks for the negative

I have a problem when using nnet to predict the negative values. For example : X = matrix(c(1,1,0,0,1,0,1,0),4,2) X Y = matrix(c(0,1,1,0)) - 0.5 # XOR - 0.5 Y nn = nnet(X,Y,size=3) val = predict(nn,X) val # this is expected to be close to Y, but it's not ! The 'val' is always positive. I tried to change the options, but the result isn't much better. Could someone give me an

I just started to write tiny functions and therefore I appologise in advance if I am asking stupid question. I wrote a tiny function to give me back from the original matrix, a matrix showing only the values smaller -0.8 and bigger 0.8. y<-c(0.1,0.2,0.3,-0.8,-0.4,0.9) x<-c(0.5,0.3,0.9,-0.9,-0.7,0.3) XY<-rbind(x,y) extract.values<-function (x) { if(x>=0.8|x<=-0.8)x

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 machine where my initial session is running. Can anyone refer me to a link that
