Examples
# not running below examples in R CMD check to save time
result <- qgis_run_algorithm(
"native:buffer",
INPUT = system.file("longlake/longlake_depth.gpkg", package = "qgisprocess"),
DISTANCE = 10
)
# most direct approach, autoselecting a `qgis_outputVector` type
# output from the `result` object and reading as sf object:
sf::st_as_sf(result)
# if you need more control, extract the needed output element first:
output_vector <- qgis_extract_output(result, "OUTPUT")
sf::st_as_sf(output_vector)
