proj_trans() is no longer supported with list input, and returns matrix output.
PROJ >= 6 is now a hard dependency (#42)
Deprecate ok_proj6() (#42)
Add {wk} transformer api (#44, #46, #48, #50)
Replace proj_trans() with S3 generic (#56)
New function proj_version().
reinstated proj function!
ok_proj6() is now meaningful again.
Deprecated old proj_trans_generic().
New function ‘proj_crs_text()’ to convert from one CRS text format to another.
No set up on load now, all handled by libproj. Package should always function, always with version 7 or above.
FIXME: (should deprecate) Removed
ok_proj6()
Now importing libproj, to provide cross platform access to PROJ version 7 and above and for configuration of metadata files.
Incorporated fixes and improvements from Dewey Dunnington.
Now using Github Actions to test linux, windows, macos. Many thanks to James Balamuta for guidance on how to do this.
The internal C functionality calling the PROJ library now uses
.Call rather than .C. The .C function
PROJ_proj_trans_generic() is now not used and will be
removed.
On load behaviour has changed, on Windows and MacOS a check is
made for a local copy of the proj/ PROJ data directory with metadata
files. If this is present, the path to that folder is set using the
underlying PROJ library function
proj_context_set_search_paths().
This is only relevant to Windows and MacOS static builds, these are self-contained, the R package contains the PROJ library and everything it needs. Generally in other installations (brew on MacOS, apt install, or from source builds on Linux) the PROJ library self-configures and knows where to find this directory.
This is automatic for source builds on Windows which download pre-built binaries and data from https://github.com/rwinlib, and so will be using a given PROJ version.
On MacOS, this only occurs if configure options
--with-data-copy=yes and --with-proj-data=DIR
are used. This is done manually on CRAN by admins. The current version
used can be found at https://mac.r-project.org/libs-4/.
Need proj version 6.1.0 or above, and a configuration fix on MacOS for libsqlite thanks to Brian Ripley, and CRAN.
Fixed bug not returning transformed z or t.
Windows: update to proj 6.3.1
We now use the PROJ::proj_trans internally, and just loop over vectors. (so proj_trans_generic is a misnomer, technically).
Prevent error on out of bounds values from
proj_trans_generic(). We get Inf.
Attempt to fix errors on CRAN, add missing test for functionality with required lib-proj version and use more generic initialization string.
New function [proj_create()] to generate CRS formats from various input types.
Removed CPP variable from configure thanks to CRAN.
Sorted out .C registration.
Now set data directory for installed share files, thanks to Jeroen Ooms for the nudge in the right direction with the R API.
Cleaned up CI testing, so we get tested on versions 5, 6, and 7 of PROJ on travis.
Removed proj_trans(), only function is proj_trans_generic() more closely aligned to the API of PROJ itself (=> 6).
Included PROJ library tooling for Windows, thanks to Jeroen Ooms.
R function proj_trans() gains a quiet
argument to control output of warnings about missing values.
New C functions R_proj_trans_FWD() and
R_proj_trans_INV() using the base R API. Interface is
matrix in, matrix out always with three columns out as per
reproj.
First working code with Rcpp function
proj_trans_cpp().
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
