Compute a suitable resolution for a map

Compute a resolution in the original map units that conforms to given criteria.

resolution(x, min_ncells = 100)

Arguments

x	a Raster* or Spatial* object
min_ncells	Number of cells for the smallest dimension

Value

A number. The resolution that respects the desired number of cells.

Examples

  r <- raster::raster(nrows = 5, ncols = 11, xmn = 0, xmx = 11, ymn = 0, ymx = 5)
  resolution(r, min_ncells = 10)
#> [1] 0.5
