mem() no longer copies or converts its input: ‘x’ must be a double array and the DSN references its memory directly. Previously the address taken was of an internal temporary copy, eligible for garbage collection as soon as mem() returned.
C_addr now returns the address of the data of a vector (not the SEXP), as a decimal string. This is portable to Windows (where ‘%p’ omits the ‘0x’ prefix) and removes the fixed header-offset arithmetic in mem(), which is also what prevented non-double types from working.
mem() documents the GDAL >= 3.10 requirement to set GDAL_MEM_ENABLE_OPEN=YES, and the lifetime contract for the referenced memory.
Native routine registration now actually occurs (the init function was misnamed R_init_addr, so registration silently never ran).
unprefix() strips exactly one leading driver prefix and no longer eats Windows drive letters or subdataset paths; unvsicurl() is anchored to the start of the string.
Removed unexported experimental rds().
Add vsis3 and vsizip.
All data source functions have been removed to sds.
New internal C_addr, to replace lobstr import.
vsicurl() gains pc_url_signing with the
sign arg (GDAL >= 3.5).
All data source functions have been removed to hypertidy/sds, so countrycode no longer needed.
New nsdic_seaice() for the GeoTIFF images.
New srtm15() source.
Add internal lists of tasmap_sources.
Fix gebco to use ice surface, add bedrock option for 2023 (thanks to Philippe Massicotte).
Clarify which gebco() functions return bedrock vs. ice surface.
New ‘nasadem()’ for the OpenTopo VRT.
dsn now contains the source functions that whatarelief had, whatarelief imports them and re-exports some.
New functions for ‘datatype()’ .
New mem() function to reference an in memory
array.
New functions sds() and
vrtcon().
First basic functions.
