| calculate_cell_size {geogrid} | R Documentation |
Given an input multipolgyon spatial data frame this function calculates the required cell size of a regular or hexagonal grid.
calculate_cell_size(shape, shape_details = NULL, learning_rate = 0.03,
grid_type = c("hexagonal", "regular"), seed = NULL,
verbose = FALSE)
shape |
A 'SpatialPolygonsDataFrame' object representing the original spatial polygons. |
shape_details |
deprecated. |
learning_rate |
The rate at which the gradient descent finds the optimum cellsize to ensure that your gridded points fit within the outer boundary of the input polygons. |
grid_type |
Either 'hexagonal' for a hexagonal grid (default) or 'regular' for a regular grid. |
seed |
An optional random seed integer to be used for the grid calculation algorithm. |
verbose |
A logical indicating whether messages should be printed as the algorithm iterates. |
