Usage

fillGrid(pointMap, fillX, fillY, copyMap = TRUE, verbose = FALSE)

Arguments

pointMap: The input PointMap
fillX: X coordinate of the fill points
fillY: Y coordinate of the fill points
copyMap: Optional. Copy the internal sala map
verbose: Optional. Show more information of the process.

Value

A new PointMap with filled points

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")
lineStringMap <- as(sfMap, "sf")
mapRegion <- sf::st_bbox(lineStringMap)
pointMap <- createGrid(
  minX = mapRegion[["xmin"]],
  minY = mapRegion[["ymin"]],
  maxX = mapRegion[["xmax"]],
  maxY = mapRegion[["ymax"]],
  gridSize = 0.04
)
pointMap <- blockLines(
  pointMap = pointMap,
  lineStringMap = lineStringMap[vector()]
)
fillGrid(
  pointMap = pointMap,
  fillX = 3.01,
  fillY = 6.7
)
