Create either a rectangular or hexagonal two-dimensional grid

Usage

hotspot_grid(data, cell_size = NULL, grid_type = "rect", quiet = FALSE, ...)

Arguments

data: sf data frame.
cell_size: numeric value specifying the size of each equally spaced grid cell, using the same units (metres, degrees, etc.) as used in the sf data frame given in the data argument. If this argument is NULL (the default), the cell size will be calculated automatically (see Details).
grid_type: character specifying whether the grid should be made up of squares ("rect", the default) or hexagons ("hex").
quiet: if set to TRUE, messages reporting the values of any parameters set automatically will be suppressed. The default is FALSE.
...: Further arguments passed to link[sf]{st_make_grid}.

Value

A simple features tibble containing polygons representing grid cells.

The grid will be based on the convex hull of data, expanded by a buffer of cell_size / 2 to ensure all the points in data fall within the resulting grid.
