Distance between grid square codes — grid

If grid and grid_to are both vectors, the distance between grid and grid_to is calculated. If grid is a list, The path distance of each element is calculated.

Usage

grid_distance(
  grid,
  grid_to = NULL,
  close = FALSE,
  type = c("keep_na", "ignore_na", "skip_na")
)

Arguments

grid: A grid vector or a list of grid vector.
grid_to: A grid vector.
close: Should the path of each element be closed when grid is a list?
type: How is the NA grid treated when grid is a list? "skip_na" skips the NA grid and connects the paths. "keep_na" by default.

Value

A double vector.
