Question

I have a data like this

y<-c("00:00:10", "00:10:10", "2:10:2")

These data are in H:M:S format. I would like to be able to convert this data to total seconds. I like to get H data multiply that with H*60*60 + M*60 + S to calculate the value in total seconds.

I was doing this:

z <- strptime(, "%H") 

to get the Hour value, not working. Can anybody chime in?

Answer 1

I have never gotten the hang of handling time in with sophisticated packages. Here’s a oneliner that does it instead.

> apply(sweep(sapply(strsplit(y, ":"), as.integer), 1, 60^(2:0), "*"), 2, sum)
[1]   10  610 7802
