[R] getting raster layer between December and march in 1-year raster

[Ben Tupper]

Hi,

I encourage you to subscribe the r-sig-geo mailing list for questions
regarding geospatial data handling.  Subscribe here...

While you have shown your code, you have been very specific about what the
issue is and how you know it is not working.  Without more information, it
really isn't possible for anyone not sitting at your computer to
diagnose the issue you are having.  Can you make a reproducible example
that shows the problem?

Best wishes,
Ben
