Create an All-line Map

Usage

makeAllLineMap(boundsMap, seedX, seedY, verbose = FALSE)

Arguments

boundsMap: The boundary ShapeMap to create the all-line map in
seedX: X coordinate of the seed (the point that initiates the process)
seedY: Y coordinate of the seed (the point that initiates the process)
verbose: Optional. Show more information of the process.

Value

An All-line Axial ShapeGraph

Examples

mifFile <- system.file(
    "extdata", "testdata", "simple",
    "simple_interior.mif",
    package = "alcyon"
  )
  sfMap <- st_read(mifFile,
    geometry_column = 1L, quiet = TRUE
  )
  shapeMap <- as(sfMap[, vector()], "ShapeMap")
makeAllLineMap(
  shapeMap,
  seedX = 3.01,
  seedY = 6.7
)
