Hi Duncan,
In this case they all had length 1, but I'll be careful at other occasions.

Be careful, it might not give you the same answer.
I'd use this variation on the advice from ?ifelse:
new.date <- my.date + x
new.date[is.na(my.date)] <- min(default.date) + x
The thing to watch out for in t
I did not know this function, thanks a lot Gabor.

Thanks Duncan, I'll go back to if and else!

See ?ifelse. The class of the result is the same as the class of the
test, not the classes of t
Hi,
I was "losing" my dates in a script and upon inspection, found that my recent
switch from separate "if" and "else" to "ifelse" was the cause. But why?
my.date = as.POSIXct("2011-06-04 08:00:00")
default.date = seq(as.POSIXct("2011-01-01 08:00:00"), as.POSIXct("2011-09-01
08:00:00"), length=
