RangeShiftR // Full R input

This is a development version of RangeShiftR

It is published here as supplementary material to the publication

"Fitting individual-based models of spatial population dynamics to long-term monitoring data"

by Anne-Kathleen Malchow, Guillermo Fandos, Urs G. Kormann, Martin U. Grüebler, Marc Kéry, Florian Hartig, Damaris Zurell.

This version can run without any file inputs or outputs and instead takes input maps as matrices from R.
Inputs such as habitat maps can now be given as matrices in R and the output abundance maps are (optionally) returned as raster objects.
(Note: the output type that is stored in these return rasters is currently hard-coded and is here set to the number of adult individuals in each cell. Adults are all stages with strictly positive fecundity.)
Avoiding the file connection saves runtime and facilitates thread safety as needed for parallel code execution.
Further, a new feature allows all demographic rates to vary spatially and temporally.
