The function check that GDAL is installed and updated to the minimum required version (2.1.2).
check_gdal(abort = TRUE, gdal_path = NULL, force = FALSE,
full_scan = FALSE)
Logical parameter: if TRUE (default), the function aborts in case no GDAL installation is found; if FALSE, a warning is shown and FALSE is returned.
(optional) Character: the path in which GDAL must be searched in. If NULL (default), search is performed in the whole file system.
(optional) Logical: if TRUE, install even if it is already
installed (default is FALSE). Notice that, defining gdal_path
, GDAL is
searched again even if "force" = FALSE
in case the existing installation
is not in gdal_path
.
(optional) Logical: in Linux and MacOS, if gdal_path
was
not manually defined, GDAL is searched within the system path in case this
argument is left to default value FALSE; instead, if TRUE, a full search is
performed. In Windows, if the default OSGeo directory C:\OSGeo4W64
exists,
GDAL is searched there, instead in the main directory C:\
; setting
full_scan
to TRUE, is is always searched in the whole C:\
.
This argument takes no effect if gdal_path
was defined, since, in that case,
a full search is always performed in gdal_path
.
Logical (invisible): TRUE in case the installation is ok, FALSE if GDAL is missing and abort=FALSE (otherwise, the function stops).
