similar to: time difference error

Dear R users, I created a matrix that tells me the first day of use of a category by id. #Calculate time difference test$tdiff<-as.numeric(difftime(as.Date("2002-09-01"), test$ftime, units = "days")) # obtain the index date per person and dcategory index.date.test<-tapply(test$tdiff, list(test$id, test$rcat), max) Nonetheless, at the moment I think will be

Dear ALL I have this function in R: func_LN <- function(data){ med_ge <- matrix(c(rep(NA,nrow(data)*ncol(data))), nrow = nrow(data), ncol=ncol(data), byrow=TRUE) T <- matrix(c(rep(NA,length(n)*ncol(data))), nrow = length(n), ncol=ncol(data), byrow=TRUE) Tdiff<- matrix(c(rep(NA,length(n)*ncol(data))), nrow = length(n), ncol=ncol(data), byrow=TRUE) T1<- c(rep(NA,ncol(data)))

Dear All, I have a pair of .cpp and .def file can be compiled using VC++ and works perfectly well in S-PLUS. I wanted to do the same for R; so I followed the guidline given in "Building from a source-code library under Windows" as much as possible and manage to compile them using VC++ and call it from R. But it gives different answer from the one called from S-Plus. I know that I did

Dear all, I found this strange behavior, when inspecting some legacy build that did not compile after an upgrade of several libraries and clang: https://stackoverflow.com/questions/44846377/what-is-the-reason-behind-instable-type-traits I got no conclusive answer, but a comment that indicates that this might indeed be a bug in clang. Since I am neither a C++ expert nor familiar with clang, I

Debuggers, I wrote to r-help about this and was appropriately told off by Peter Dalgaard. I append that mail in case you have not seen it. Following Peter's advice I have attempted to simplify the problem. First note that the following does *not* fail (by which I mean crash, as in generate a memory access violation): > tmp<-matrix(c(1,0,0,1,1,1),2,3) >

Hi, the updated Amazon Web Service AMI (ami-4ac6653d) has a serious bug. It is not possible to resize a disk after creating a new volume with a size greater than 8GB. resize2fs does nothing.
