Converting column from military time to standard time
Question:
Tag: r,excel
I'm trying to convert a column showing the time of road traffic accidents from military time to standard time. The data looks like this:
Col1 Time..24hr.
1 1404
2 322
3 1945
4 1005
5 945
I'd then like to convert to 12hr so for '322' I'd like to make '3', for instance. Thanks a lot
Answer:
Given your criteria -- that 322 is represented as 3 and 2045 is 20 -- how about dividing by 100 and then rounding towards 0 with trunc().
time_24hr <- c(1404, 322, 1945, 1005, 945)
trunc(time_24hr / 100)
