create_resistances: Estimates resistance rasters from binary feature raster.

In MarianaLag/Mlag: Tools Related to the Spatial Analysis of Genetic Marker Data

Description

This function produces a cost raster from a single value

Usage

create_resistances(
  x,
  feature_name = "layer",
  costs = c(2, 5, 10, 50, 100),
  symmetric = TRUE
)

Arguments

x	A base raster object from which to base others.
feature_name	The prefix for output files for this raster feature (default='layer').
costs	A vector of cost rasters to iterate across (default=c(2, 5, 10, 50, 100)).
symmetric	A flag indicating that costs out of as well as into features will be estimated.
