  • Fixed issue lonlat=TRUE when calculating step lengths (#103, #107, #108)

amt 0.2.1

Fixes

  • The correct step id is now given in random_steps.brusted_track_xyt().

amt 0.2

updates

  • Removed dependency on Rccp, all code is now in R.
  • extract_covariates() no longer accepts a buffer.
  • Updated time_of_day() to use suncalc instead of maptools.
  • Updated hr_overlap() from raster to terra.

  • Major updates for hr_akde. This includes that now CI are available for
  • new vignette and methods for hr_overlap
  • reduced package dependencies.
