[R] Calculate Averages for time data

[Gabor Grothendieck]

Next time please provide sample input.

library(chron)

# input
ch <- c("02:24:00", "04:48:00", "07:12:00", "09:36:00", "12:00:00",
"14:24:00", "16:48:00", "19:12:00", "21:36:00")

# convert to times
tt <- times(ch)

# calculate mean
mean(tt)
