GDALDriver
objects encapsulate GDAL file format
drivers. GDALDriver
inherits from GDALMajorObject-class
.

driver |
An object inheriting from class 'GDALDriver' |
str |
A string, may be one of |
getGDALDriverNames, gdalDrivers
:returns all driver names currently installed in GDAL, with their declared create and copy status (some drivers can create datasets, others can only copy from a prototype with a different driver.
getDriverName
:returns the GDAL driver name associated with the driver object.
getDriverLongName
:returns a longer driver name.
getGDALVersionInfo
:returns the version of the GDAL runtime shared object.
Objects can be created by calls of the form new("GDALDriver", name, handle)
, where name: a string giving the name of a GDAL driver, handle: used internally; not for public consumption (default = NULL).
handle
:Object of class "externalptr", from class "GDALMajorObject"
, used internally; not for public consumption
Class "GDALMajorObject"
, directly.
signature(.Object = "GDALDriver")
: drivername: a string giving the name of a GDAL driver, handle: used internally; not for public consumption (default = NULL)
Loading the rgdal package changes the GDAL\_DATA
environmental variable to the GDAL support files bundles with the package.
