sf_LatLongGrid: Make polygon grid over 'sf' feature using lat-lon coordinates

In jacpete/jpfxns2: Second Interation of JP Functions - Purdue Edition

Description

Make polygon grid over sf feature using lat-lon coordinates. This can be used to split data into regions determined by the exported grid. Can be used to create a standard grid using the bounding box of the original feature or a 'pretty' grid that locks grid edges to more even numbers.

Usage

sf_LatLongGrid(
  sfLayer,
  gridSize = 1,
  prettyGrid = TRUE,
  epsg = 4269,
  output = c("polygon", "raster")
)

Arguments

sfLayer	sf object
gridSize	grid resolution, uses coordinate system measurement. Default: 1
prettyGrid	logical, Use pretty grid measuremetns? Defalut: TRUE
epsg	an EPSG key
output	character, Do you want a polygon or raster output of the estimated grid?

Value

Returns either a raster or sf Polygon grid to overlay over the sfLayer data.
