Overview

About

Maintained by Michael SumnerCRAN page ↗GitHub ↗Website ↗Issues ↗

Simple helpers for 'GDAL' data source names ('DSN'), prefix and suffix and other handling. 'GDAL' is the Geospatial Data Abstraction Library https://gdal.org/, not used by this package directly.

Changes in 0.1.0

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.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("dsn", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("hypertidy/dsn")

Development version from hypertidy/dsn. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-dsn

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-dsn

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-dsn

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
