RSAGA 1.0.0 has been released on CRAN. The RSAGA package provides an
interface between R and the open-source geographic information system
SAGA, which offers a variety of geoscientific methods to analyse spatial
data. SAGA GIS is supported on Windows, Linux, Mac OS and FreeBSD and is
available from
sourceforge.

After a long break in the development, RSAGA now supports SAGA GIS 2.3
LTS to 6.2.0. The main issue with the maintenance of RSAGA lies in the
changing names of the parameters used by the SAGA command line program.
These parameters are essential to provide the user with wrapper
functions like rsaga.slope.asp.curv and rsaga.wetness.index. We were
able to update all parameter names, while keeping the support for older
SAGA versions.

RSAGA is able to find SAGA installations on Windows, Linux and Mac OS
automatically again with the build-in function rsaga.env. For new
users we would like to refer to the updated
vignette.

Further development will go into the integration of Travis CI to test
new SAGA versions automatically. We would like to reduce the effort of
maintaining the list of parameter names. A solution could be the
collaboration with the recently started
Rsagacmd project, which uses
the html help files of SAGA GIS to get the parameter names.

The development of RSAGA is now integrated into the r-spatial.org
community. If you find any bugs please report them at our new
development repository
r-spatial/RSAGA. We are happy
about every project that involves RSAGA. Please help us with bug
reports, new ideas and feedback. Stay tuned for further updates.
