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 more useful to create a column in m...

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))) T0<- c(rep(NA,ncol(data))) cov_rank<-matrix(c(rep(NA,ncol(data)*ncol(data))), nrow = ncol(data), ncol = ncol(data) , byrow=TRUE) med <- c(rep(NA,ncol(data))) mean_ge &...

Hello! I have a problem making a new variabel in a dataframe that consists of a time difference. It seems that the new variable gets into the dataframe but I cant look at it anymoore.

...ng through the code of rsync it looks like there is problem in msleep function. It uses gettimeofday linux API. If system clock time changes between two successive calls to this function then the time difference will be a very large value which is getting assigned to a 32bit signed integer variable tdiff. Since that time difference is larger than 2^31, tdiff finally gets a large negative number. this number is passed as positive value in the select call used for sleeping. Thus ultimately leading to rsync hang for a very large amount of time. In my case it hanged for 550hrs. I tried to assigned NTP...
