st: hours and minutes help
I was wondering if any of you know of a method for creating 2 new variables from 1 variable, with 1 of the new variables containing whole numbers and the second new variable containing the numbers after a decimal point.
I am asking this because I have time data (hours: minutes) in which the hours and minutes are separated by a decimal point instead of a colon (so 6:45 AM is expressed as 6.45, not 6.75).
I have 2 variables: starttime and endtime. I need to subtract start-times from the end-times, which I cannot due with the present variable format. I was thinking of using the "hmm" function that is part of the -egenmore- package. But I need to separate the hours and minutes and this is where I get stuck.
I would greatly appreciate any advice you could give me.
