...r using it with levelplot. So far I could only find examples showing how to sort alphabetically. Here is a short example:? a <- c("Anna","Anna","Michael","Klaus","Klaus","Anna","Fritz")? b <- c("Schnitzel","Pommes","Pommes","Schnitzel","Wurst","Schnitzel","Schnitzel")? food <- matrix(c(a,b),7) as.data.frame(food) -> tmp? as.data.frame(table(tmp)) -> X levelplot(X$Freq ~ X$V1 * X$V2,xlab="people",ylab="food")? Food is now ord...

Dera R helpers, I have a (x,y,z) data file where x and y are spatial coordinates and z a variable. I have some missing values in the z column and I would like to replace them with an optimized estimation from the neighbour cells. I could not find any function in R to do that. Is anybody aware of such function ? Maybe someone knows how to implement the Papadakis method in R... Thanks for your

Hello all. I have just installed R version 1.6.1 for Windows on a XP machine. I would like to use R in batch mode. For this, I looked for Rcmd.exe, but did not find it. Any hint where it could be?

Dear r-helpers, Prior to analysis of variance, I ran the Boxcox function (MASS library) to find the best power transformation of my data. However, reading the Boxcox help file, I cannot figure out if this function (through its associated log-likelihood function) corrects for * normality only * or if it also induces * homogeneity of variances *. I found in Biometry (Sokal and Rohlf, p. 419)

Dear all, after having calibrated a svm model through the svm() command of the e1071 package, is there a way to i) represent the modeled relationships between the y and X variables (response variable vs. predictors)? ii) rank the influence of the predictors used in the model? Right now I am more interested in regression models, but I guess this would be useful for classification too. Thank

Dear all, I am currently looking for a book about support vector machines for regression and classification and am a bit lost since they are plenty of books dealing with this subject. I am not totally new to the field and would like to get more information on that subject for later use with the e1071 <http://cran.r-project.org/web/packages/e1071/index.html> package for instance. Does
