[R] CRAN - Package "activity" - how do you convert time (hh:mm) into radians in R 3.1.2 on Windows 7 OS 64bit
Hello, I am using the "activity" package developed by Marcus Rowcliffe (released in February, 2015). This package uses time in radians to estimate activity. I have camera trap data in 24 hour times (hh:mm) - how do I convert these into radians? (e.g. My time-of-detection at 19:44, how do I convert this into radians?) Thank you for your time and your help [[alternative HTML version deleted]]

Hint: 24 hours = 24x60 = 1440 minutes = 2 pi radians. Cheers, Bert Bert Gunter "Data is not information. Information is not knowledge.

Hi Typhenn, Have a look at clock24.plot in the plotrix package.
