Initialize an R object containing spatial data for use by WhiteboxTools

Usage

wbt_source(
  x,
  dsn = NULL,
  layer = NULL,
  force = FALSE,
  tmpdir = tempdir(),
  pattern = "wbt",
  verbose = wbt_verbose(),
  ...
)

Arguments

x: A terra SpatVector or sf object (in memory) or a path to a file that can be read as a SpatVectorProxy. Or a memory or file-based SpatRaster. When x has multiple layers/bands, the first layer is used by default; use the layer argument to select a specific layer/band.
dsn: Data source path / file name
layer: Data layer. For vectors, layer is interpreted as a layer name (character); for rasters, layer is interpreted as a band index or name (integer OR character)
force: Force write of vector data to file? Default: FALSE (only write if file does not exist and new file is needed)
tmpdir: Directory to write temporary ESRI Shapefiles for vector input in memory or otherwise not already in shapefile. Default: tempdir()
pattern: Character vector giving the initial part of the temporary file name
verbose: Print information about data source and contents?
...: Additional arguments passed to terra::writeVector() or sf::st_write(), or terra::writeRaster (for rasters).

Value

An R object (SpatRaster, SpatVector, SpatVectorProxy, sf) with attributes wbt_dsn and wbt_layer set as needed to support reading and writing R objects from file by WhiteboxTools.
