rtSetVegMoveGrids: to return an array of grids used internally to represent...

In AndySouth/rtsetse: simulating tsetse fly populations

Description

Used to represent effect of vegetation in a cell on movement out of that cell. Returns an array of movement multiplier grids to N,S,E & W

Usage

rtSetVegMoveGrids(mVegCats = array(c("O", "O", "O", "O", "S", "O", "O", "O",
  "O", "O", "O", "O"), dim = c(3, 4)), dfMoveByVeg = data.frame(code = c("D",
  "T", "O", "S", "B", "G", "N"), move = c(0.85, 0.9, 0.95, 1, 1.05, 1.1, 0)),
  mVegMove = NULL, verbose = FALSE)

Arguments

mVegCats	a matrix of vegetation categories
dfMoveByVeg	dataframe specifying a movement multiplier for each vegetation category
mVegMove	optional matrix of vegetation movement modifiers >1 increases movement out of the cell, <1 decreases movement out of the cell
verbose	print what it's doing T/F

Value

an array of movement multiplier grids 'here' and to N,S,E & W

rtSetVegDifGrids which sets up similar grids for influencing movement according to vegetation differences between cells.
rtMove uses the grids created.
