- Make the test for the correct Python path more generic in
setup_win()
since one user has named the QGIS folderbin
(commit 0588716)
- Making sure that RQGIS does not return the same result when using same parameters names (e.g., INPUT). See #82 and 494e666. Thanks to @lbusett for suggesting a solution.
- Updating
random_points
in accordance with issue r-spatial/sf#685 set_env()
now also searches forqgis-ltr.bat
- new example data
comm
andstudy_area
added - updating
install_guide
vignette
- Linux:
qgis_session_info()
now tries several times to find out about the installed GRASS version (find
frequently fails at the first attempt when used witin a function), and additionally suppresses a confusing warning message regarding access rights (permission denied when trying to access points.shp, however these points are accessed regardless of this message since they are used to test if GRASS can be accessed which is the case). - If a user specifies simply a basename for an input or output file,
run_qgis()
will now look for this file in the working directory (getwd()
) or save it to this locations (suggested by @rkrug). - Specifying all parameters of a QGIS geoalgorithm in the "wrong" order caused an error. Issue #87 and solved through https://github.com/jannes-m/RQGIS/commit/45aef93c22107b2f34ee5ce4aa16cec485fc9489 (@raff-k).
qgis_session_info()
no longer prints the supported saga versions if there is nothing to report (methodsupportedVersions
was deleted fromSagaAlgorithmProvider
since QGIS 2.18.10).run_qgis()
accepts network addresses as filenames under Windows again (#735e856, @susanatfybr).run_qgis()
,pass_args()
andsave_spatial_objects()
now have an additional parameter namedNA_flag
, which allows to specify a value for NAs when exporting rasters (issue #93 raised by @raff-k and solved through #9e74a4a ).
get_args_man()
,run_qgis()
andpass_args()
now print which default options were chosen (suggested by @rkrug).- More extensive testing through a new test file (
test-paper-analysis
) get_grp()
was replaced by the more genericget_extent()
. If a geoalgorithm requires an extent object it will be computed automatically from the provided input spatial objects (if not specified explicitly by the user) (#95).
- making sure that
setup_win()
works properly when the working directory is a server (commit ccc1baa & 263a1cf) - solving winslash problems occurring in conjunction with Python, e.g., when in tempdir() directory names start with \n or \t (see commits 484e1d3, 8befac3 and issue #71)
set_env()
now uses forward instead of backward slashes (commit 8befac3 and issue #83)- making sure under Linux that the decimal operator is a colon not a comma with the help of Sys.setlocale (see commit f3c7e15)
- making sure that default parameter values will not be overwritten by
RQGIS.check_args
(commit 29fb26a and issue #79) - reticulate 1.1 caused some trouble due to json parsing in
conda_list()
(solved by: rstudio/reticulate#100; @jjallaire).
- RQGIS now supports FreeBSD (#78, @rhurlin)
- merging python_funs.py and import_setup.py into python_funs.py
- New function parameter
show_output_paths
inrun_qgis
. Setting it toFALSE
suppresses the printing of the output file paths. random_points
is now an sf-object (required also some adjustments in run_qgis and our tests)run_qgis
doesn't print a space any longer if the Python message is empty- developing and improving test coverage
- adding GDAL version to
qgis_session_info
load_output
now supports all GDAL-supported drivers. Of course, this depends on the system setup (#72).- deleting deprecated function arguments
show_msg
andcheck_params
(run_qgis
) - deleting deprecated function argument
ltr
(set_env
)
- RQGIS now uses reticulate to establish a tunnel to the QGIS Python API (instead of starting a new Python session each time a function is called; #59). Consequently, we had to rewrite all RQGIS functions. Internally, the Python session is established by calling the new function
open_app
.open_app
in turn makes advantage of various new helper functions (setup_win()
,run_ini()
,setup_linux()
,setup_mac()
). Additionally, we put much of the Python code into inst/python.import_setup
contains much of the necessary import statements to run QGIS from within R.python_funs
contains the RQGIS class (#32) containing several methods to call from within R (get_args_man()
,open_help()
,qgis_session_info()
, etc.).
-
The user can now specify QGIS geoalgorithm parameters as R named arguments using the ellipsis-argument
...
(#58). -
We rewrote the
load_output
-argument ofrun_qgis
. It is now a logical argument. IfTRUE
,run_qgis()
will automatically load all the output layers explicitly specified by the user back into R (#60). -
Extensive error-/misspecification checking. To do so, we now submit a Python-dictionary - containing all parameters and arguments - to
processing.runalg
. This also allows to check parameter names. Before the **args-argument simply converted our input in a list containing the arguments (but not the parameter names). Using the Python dictionary has the additional benefit that we no longer have to take care of the order in which the function parameters are specified. Besides, we now also make sure that the user can only specify available options. And if the user provides the verbal notation,pass_args
internally converts this input in the corresponding number notation as required by the QGIS API (#64, @tim-salabim; #65). -
RQGIS now supports simple features (
sf
; #43, @einvindhammers). -
support for MultiParameterInput through two new helper functions
save_spatial_objects
andget_grp
(https://gis.stackexchange.com/questions/240303/defining-grass-region-in-rqgis) -
RQGIS now supports QGIS
osgeo4mac
homebrew installations. This is also the recommended installation way from now on as it does not cause irritating error messages like the Kyngchaos QGIS binary. -
find_algorithms
now accepts regular expressions as argument for itssearch_term
parameter -
set_env()
now caches its output, so calling it a second time, will load the cached output. -
Under Windows
set_env()
now first searches the most likely places to find a QGIS installation. -
changing
set_env
's parameter name fromltr
todev
. When having multiple homebrew installations on mac (LTR and dev), the user can select which one to use with thedev
argument inset_env()
. Default uses the LTR version. -
qgis_session_info()
now warns Linux users that they might have to use a softlink when using grass7 in conjunction with QGIS (#52, @thengl) -
changing the default for parameter
options
fromFALSE
toTRUE
inget_args_man
-
reset_paths
tries to restore the PATH environment variable, i.e. at least to make sure that all paths within PATH will still be available after having runopen_app
.
- Adding new tests.
-
build_cmds
now retrieves the working directory on the command line from where the script has been called (temporary folder), and makes it the working directory at the end of the batch script. This ensures that py_cmd.py can be found and executed (necessary since QGIS 2.18.2 since they somehow change the wd in one of their .bat-files) (#26, @eivindhammers). -
RQGIS now also does testing using the
testthat
-package (#20). -
run_qgis
stops if the user specifies one of the interactive QGIS Select-by operations. -
run_qgis
now stops if the output shapefile created by QGIS is empty. -
run_qgis
-message: Use qgis:creategrid instead of qgis:vectorgrid. -
Fine-tuning of the documentation files.
-
Deleting redundancies in functions
build_cmds
,check_apps
andexecute_cmds
. -
Removing empty string from
find_algorithms
output. -
Added a
NEWS.md
file to track changes to the package. -
vignette update (MacOSX and homebrew installation) (#14, @pat-s)
-
bug fix: we replaced
findstr
inset_env
by the more general%SystemRoot%\\System32\\findstr
. -
bug fix: when constructing the cmd-command (in
run_qgis
), we need to avoid "double" shell quotes. This happened e.g., withgrass7:r.viewshed
. Additionally, we made sure that None, True and False are not shellquoted. -
bug fix: when determining the GRASS REGION PARAMETER in
run_qgis
. To extract the extent of a spatial objectogrInfo
needs the layer name without the file extension. To do that we now use thefile_path_sans_ext
of thetools
package instead of a simplegsub
-command. Previously, we simply returned everything in front of a colon. This caused problems with file names such as gis.osm_roads_free_1.shp. -
bug fix:
run_qgis
function argumentload_output
now checks if the QGIS output was really created before trying to load it. -
bug fix: There was a problem when using QGIS/Grass on a MacOS. Deleting one bash statement (
paste0("export PATH='", qgis_env$root, "/Contents/MacOS/bin:$PATH'"))
) solved the problem. -
bug fix:
qgis_session_info
now also runs on MacOS (#34)
- Initial CRAN release
