These functions create temporary files that can be used
in calls to qgis_run_algorithm()
or elsewhere. These
files are created in a special temporary directory
(qgis_tmp_base()
) that should be periodically cleaned up
using qgis_clean_tmp()
. You can set your preferred
vector and/or raster file extension using
options(qgisprocess.tmp_vector_ext = "...")
and/or
options(qgisprocess.tmp_raster_ext = "...")
, respectively.
