?I compiled a program on my Apple MacBook that takes as inputs
Year and Month and Day
Latitude and Longitude
And then computes these two outputs
Sunrise Year-Month-Day Hour:Minute:Second
Sunset Year-Month-Day Hour:Minute:Second
It automatically handles Daylight Savings Time.
A typical input, followed by the automatically computed outputs looks likes this.
./sunrise_05 2022 01 1 38.8586314239524 77.0512533684194

I want to use R?s lines() command to show the sunrise and sunset times for the year 2012. How do I tell R that the first computed output is sunrise, and the second computer output is sunset?
