Question

I am trying to identify the average time in a column of a data frame in hr:min:sec format using R. But no luck. Help is much appreciated. Data sample is as below:

Answer 1

We can do this without using any external packages

format(mean(strptime(Col_Time, "%H:%M:%S")), "%H:%M:%S")
#[1] "03:17:26"

data

Col_Time = c('03:08:20','03:11:30','03:22:18','03:27:39')
