Snap state offsets to a grid

Rounds every region and label offset in a d_state() to the nearest multiple of grid, tidying hand-dragged layouts into even increments.

Usage

d_snap_offsets(state, grid = 1000)

Arguments

state

A dragmapr_state object.

grid

Single positive number in metres. Offsets snap to the nearest multiple of grid.

Value

An updated dragmapr_state with a bumped version.

Examples

state <- d_state(
  region_offsets = data.frame(region = "A", dx_m = 1234, dy_m = -567)
)
state <- d_snap_offsets(state, grid = 1000)
state$region_offsets
#>   region dx_m  dy_m
#> 1      A 1000 -1000
