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

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
