I think you mean to use if instead of ifelse (and you should probably read briefly on the difference between them: if is the regular programming construct: ifelse is a vectorized thing) if(length(theData) == 0) t0 <- t0 else t0 <- theData which can be more expressly written as t0 <- if(length(theData)==0) t0 else theData Michael Weylandt

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. Many thanks, Helena -- View this message in context: http://r.789695.n4.nabble.com/Library-chron-tp3935969p3935969.html Sent from the R help mailing list archive at Nabble.com.
