circuitscaper 0.1.1

New features

• New os_condition() constructor gives os_run() full access to Omniscape’s conditional connectivity (#2):
  • "within" comparisons with user-specified bounds (lower, upper).
  • Present-vs-future comparisons (future), in which sources’ present-day values are compared against targets’ future values, as in climate-tracking connectivity analyses.
  • Two simultaneous conditions, by passing a list of two os_condition() objects.
• os_run() now warns when a condition layer has missing values at source cells, which Omniscape does not filter.
• All cs_*() functions and os_run() now warn if the installed Circuitscape.jl or Omniscape.jl does not recognize a configuration option written by circuitscaper, rather than letting the option silently have no effect.

Bug fixes

• In 0.1.0, os_run()’s condition_type argument was written to the Omniscape configuration under a key Omniscape does not recognize, so it was silently ignored. All conditional analyses instead used Omniscape’s defaults, "within" with bounds of 0 and 0: a source was connected to a target only if its condition value exactly equaled the median value of the target block. This was neither the documented behavior (an unbounded range) nor the requested "equal" comparison. Results from 0.1.0 that used condition should be rerun.
• In 0.1.0, four_neighbors = TRUE was written to the Circuitscape configuration under an unrecognized key and silently ignored in cs_pairwise(), cs_one_to_all(), cs_all_to_one(), and cs_advanced(); all analyses used 8-neighbor connectivity. Results from 0.1.0 that used four_neighbors = TRUE should be rerun.

Breaking changes and deprecations

• Passing a raster directly as os_run(condition = ) is now shorthand for os_condition(x, type = "equal"). Use os_condition() for "within" comparisons, which now require explicit bounds.
• os_run()’s condition_type argument is deprecated. condition_type = "equal" still works with a warning; condition_type = "within" now errors, since it has no way to specify bounds.
