Dear R users, I want to share my joy with you. Please see the following excellent introduction to R "Statistiques avec R " by Vincent Zoonekynd http://zoonek2.free.fr/UNIX/48_R/all.html In paticular, you can see a lot of fascinating graphics examples of R from which you can get many hints. Soryy if this is already well-known, but the CRAN search did not show nothing with the keyword "Zoonekynd&quo...

madame, monsieur, help me please, Je debute avec R. J'ai r??alis?? une analyse factorielle discriminante avec R. J'obtient les resultat graphiques et les tables assici??es ?? l'analyse. Cependant je souhaiterais savoir si les distances separant les groupes (decades) sont statistiquement significatives. pour cela il me faut utiliser la distance de mahalanobis et la statistique de

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 commerciales: eurostat: Pays Produit Tonnage CI 801 10123 ....... J'ai un autre frame , cp qui m'indique Produit Nom 801 Coco...

Hi, I need to do several matrix multiplications with the corresponding matrices forming two 3-dimentional arrays. To illustrate my problem, let's say I have the following 3-dimensional arrays: array1 <- array(1:30,dim=c(3,2,5)) array2 <- array(1:20,dim=c(2,2,5)) I know that I can get what I want with the following computation : result <- array(dim=c(dim(array1)[1],

No. But it has not been posted either. You got that message because you sent your message to the wrong address. You should have sent it to r-help at r-project.org You had probably sent it to r-help-request at r-project.org which would have had the effect that the server would have tried to interpret the contents of you message as commands (e.g. to unsubscribe, change your subscription

Hi Alejo, According to my knowledge the two plots are different because in the first one a point belongs to a group depending on its group in the data whereas in the second plot a point belongs to the group predicted by the linear discriminant analysis. I hope somebody will correct me if I am wrong. Alain Alejo C.S. wrote: > Hi Alain, this is the code: > > > library(MASS) >

Hi R-users, I have to define a noise level function L and its energy in the various moment of the day by: if time is between 18:00:00 and 23:59:59 then L[j] <- L[j]+5 and W <- 10^((L+5)/10) if time is between 22:00:00 and 05:59:59 ==> L <- L+10 and W <- 10^((L+10)/10) else L=L and W = W Could someone help me to realize this function please? You will find my following
