- Peut-on poser des questions en fran?ais? - Tr?s simple. Je fais un programme "truc.r" (sous emacs) Ce programme r?alise des graphiques. Je voudrais les enregistrer au fur et ? mesure -- sinon, quand la session est finie, ces graphiques sont perdus-- J'ai essay?: pdf("truc.pdf") Mais le fichier "truc.pdf" cr?? est vide. Comment fait-on? Merci et salutations

Ma premi??re question: puis-je ??crire en fran??ais, mon anglais est pire que pire. J'essaie en fran??ais; sinon, j'essaierai une traduction! Je sduis d??butant. Ma question est donc simple, j'imagine. Je travaille sur des tableaux de statistiques. Je prends un exemple: J'ai un "frame" que j'appelle "eurostat" qui me donne des statistiques

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 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 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 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

'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, 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

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

Dear Tobias, I finally succeeded in exporting my dataframes from R into Access with this script: library(RODBC) canal <- odbcConnectAccess("D:/Floristique.mdb") sqlSave(channel=canal, dat=flore, tablename="Floristique", rownames=F, safer=F, fast=F, varTypes=c(dates="Date")) odbcClose(canal) My problem in exporting my dataframe "flore" seems to

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, I got the following error message when running a function of mine doing intensive computations: Erreur dans .Call("R_lazyLoadDBfetch", key, file, compressed, hook, PACKAGE = "base") : r?f?rence d'argument par d?faut r?cursive I haven't found neither where the problem lies nor what could be recursive. Besides, I wonder whether it might or not be a problem

G'day ya all. i had a few day's off, and was able to make samba-3's first user editor (it's actualy an front-end for pdbedit!!) check out : http://213.34.118.231/pdbedit/ let me know what you think of this user manager for samba-3 Greetings. --------------------------------------------- Collen Blijenberg (Systeem/Netwerk Beheerder) Montessori Lyceum Herman Jordan Zeist

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:

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

Hi, I just found something weird for mongrel with static files.
