Extracting parts of a factor

Vote count:

I am trying to extract parts of a factor within a data.frame that look like the following:

aug$V5 <- c("00:00:00","01:01:05","04:32:22")

The format is in a factor and I want to extract the first two digits, as they are the hours that I am interested in, and place them in a different column within my vector.

Output looks like this:

aug$hours <- c("00","01","04")

I think I just need to use the sub function but am unsure.

Thanks.
