r - Convert hours:minutes:seconds to minutes

Question

I have a vector "Time.Training" in the format hours:minutes:seconds (e.g.

Time.Training <- c("1:00:00", "0:45:00", "0:30:00", "1:30:00")

I would like to convert this into minutes in the format:

Time.Training.Minutes <- c(60, 45, 30, 90)

I'm wondering if someone has a straightforward method of doing this in R.

Many thanks.

Matt

Answer 1

Using lubridate:

Time.Training<- c("1:00:00", "0:45:00", "0:30:00", "1:30:00")

library(lubridate)
res <- hms(Time.Training)        # format to 'hours:minutes:seconds'
hour(res)*60 + minute(res)       # convert hours to minutes, and add minutes
## [1] 60 45 30 90
