RQGIS 1.0.3

Bugs

• 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 45aef93 (@raff-k).
• qgis_session_info() no longer prints the supported saga versions if there is nothing to report (method supportedVersions was deleted from SagaAlgorithmProvider since QGIS 2.18.10).
• run_qgis() accepts network addresses as filenames under Windows again (#735e856, @susanatfybr).
• run_qgis(), pass_args() and save_spatial_objects() now have an additional parameter named NA_flag, which allows to specify a value for NAs when exporting rasters (issue #93 raised by @raff-k and solved through #9e74a4a ).

Features

• get_args_man(), run_qgis() and pass_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 generic get_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).
