Simulation of Demic Diffusion with Environmental Constraints

Documentation for package ‘dispeRse’ version 1.1

.to_grid	Convert from geographic coordinates in a given projection system to the relative position in rows and columns of a grid.
euro_dates	Coordinates and earliest dates (med cal BP) for European Neolithic sites. Dataset adapted from the supplementary information in Pinhasi et al. 2005 (https://doi.org/10.1371/journal.pbio.0030410).
euro_npp	Transformed Net Primary Production (NPP) from 11 ka to 4 ka at 1000 yr steps. Calculated with the Miami formula using paleoclimatic data from Beyer et al. 2020. (https://doi.org/10.1038/s41597-020-0552-1). Clipped to max=1350, squared and scaled to [0,1].
euro_terr	Reclassified terrain layer with elevation > 1750 m as barriers and rivers and coastline as corridors. Terrain reclassified from SRTM. Rivers rasterized from GSHHG (https://www.soest.hawaii.edu/pwessel/gshhg/) and coastline rasterized from rnaturalearth.
ppnb	Coordinates and earliest dates (med cal BP) for Late Pre-Pottery Neolithic B sites in the Near East. Dataset adapted from the supplementary information in Pinhasi et al. 2005 (https://doi.org/10.1371/journal.pbio.0030410).
simulate_dispersal	Simulates first arrival times from one or more origins.
