R and emacs
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

tapply and weighted means
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 ?

Applying a function to a vector
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 ?

P values in non linear regression and singular gradients using nls
Dear all, We are trying to fit a non linear model to dispersal data. It seems that sometimes when the fit of the model of the data is not very good we start getting singular gradient errors. However if we modify slightly the data this won't occurr. We have also tried changing the initial parameter values and the algorithm for fitting in nls but didn't help. So we ended up programming a

RODBC to import/export xls files
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

Warning when using 'prelim.mix' from the package 'mix'
'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,

ScalarEvolution questions
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

Samba group management understanding
Hello all, I want to set up a share for a project (enseign) First thing I did is to create a group for that project (with smbldap-groupadd) and add project members to that group. Then I created a test_smb directory on my linux server with the following access rights: drwxrwx--- 2 gbayard enseign 4096 avr 29 15:03 /test_smb Note: the idea is that only group members should be able to

Hi Sanjoy, Your inputs really helped. Using “isImpliedCond”, able to relate and find the min for cases like: SCEV1: (-1 + (sext i32 %n.addr.058 to i64))<nsw> SCEV2: 0 Extra-Condition: (n.addr.058 > 7) Result: ‘0’ (SCEV2) I have another case where trying to find min between two SCEVs under an extra condition. “isImpliedCond” is not helping for below case, may be I’m missing something:

[LLVMdev] Add/sub with carry; widening multiply
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
