GDAL warning level or get a
data.frame with the available GDAL drivers (file formats), or, if
drivers=FALSE, you get the version numbers of one or all of the GDAL, PROJ and GEOS libraries.
GDAL is the software library that terra builds on to read and write spatial data and for some raster data processing.
PROJ is used for transformation of coordinates ("projection") and
GEOS is used for geometric operations with vector data.
gdal(warn=NA, drivers=FALSE, lib="gdal") gdalCache(size=NA) setGDALconfig(option, value="") getGDALconfig(option)
drivers=FALSE, the version of the library specified by
lib is returned. Otherwise, the value should be an integer between 1 and 4 representing the level of GDAL warnings and errors that are passed to R. 1 = warnings and errors; 2 = errors only (recoverable errors as a warning); 3 = irrecoverable errors only; 4 = ignore all errors and warnings. The default setting is 3
