Hi,
I have this vector:
> A <- c("00:00:36","00:02:18")
> A
[1] "00:00:36" "00:02:18"
I use as.difftime to convert this to time vector based
> B <- as.difftime(A)
> B
Time differences in secs
[1] 36 138
attr(,"tzone")
[1] ""
Now i try to make a sum
> sum(B)
Time difference of 174 secs
The sum is ok, but how to convert this result again do H:M:S format to
get the result
00:02:54, that is 2 minutes and 54 seconds.
work with times is aways difficult, I try the units parameter in
as.difftime but dont work.
Thanks
Ronaldo
