Changelog

windscape (development version)

Breaking changes

• random_walk(): "ratchet" mode removed; results are now a named list of rasters; arguments reordered (general arguments before mode-specific ones). The new latitude correction (on by default) changes results on lon/lat grids.
• cfsr_usa and katrina datasets replaced by windscape_example().
• wind_series() and wind_rose() now require lon/lat grids with (near-)square cells.

New features

• random_walk() gains mode = "stream" (steady state of continuous release, returning residence time and deposition), half_life (deposition), and latitude_correction.
• rw_self_retention() for leave-one-out corrections of stream-mode results.
• windscape_example() loads small example data sets.

Bug fixes

• particle_flow(): east-west displacement now accounts for latitude, and ignore_speed = TRUE no longer applies scale twice.
• as_wind_rose() and read_wind_rose() now work with numeric trans.
• least_cost_distance(adjust = TRUE) no longer returns NaN on the diagonal.
• windscape no longer masks gdistance::geoCorrection().
• Removed hidden dependencies on dplyr and magrittr being attached.

windscape 1.1.0

• Initial release.
