Hi there, I have the following problem using times() and ifelse().
t0 <- c(rep("NA", 7)) theData <- times(c("07:36:00","08:09:00","10:28:00","13:28:00","16:29:00", "19:30:00","22:29:00")) t0 <- ifelse(length(theData)==0, t0,theData) In this case, R gives this, instead of theData: > t0 [1] 0.3166667 Is there a way to fix it? Any hint is welcome.
