Dear community,
this time my question has something to do with with spatial context but not in
the sense we discuss it usually here. I tried to find out if it is possible to
ask R for the location (path) of the R-file from which I send the code. What I
want to ensure is, that the R code works,
Hi Nils,
Getting the current working directory is done using getwd().
I have some comments inline below:

Is there a way to import ESRI shapfiles into RSAGA?
And if yes how can I then import it to SAGA GIS since it seems to not support
the ESRI format.
Thanks in advance

Hi,
A quick google showed that SAGA supports the GDAL library for data
import and export. This library should (specifically the OGR part)
supports ESRI shapefile (http://www.gdal.org/ogr/drv_shapefile.html). So
I think you must be more specific on which commands you used to try and
load the
Jonas,
SAGA (GUI) can read and write shape files. This is the native vector format it
uses. Maybe this is
confusing, but RSAGA is NOT a GIS package under R, but only a link to send
things from R to SAGA and
back.
Here are some examples:
Hi Don,
If your polygons are all convex, then there is hope. If not
then it can only be done with added constraints, there is
not enough information in the coordinates alone to order them
except up to an approximation. If they are convex, just
compute the convex hull. If not, you could try
Hi there,
I have a dataset consisting of measurements of tree size taken in more
than 200 forest plots along a regular grid within a forest. For each
plot, i can build summary statistics such as frequency distributions of
such characters (e.g., height, diameters, etc).
I have the expectation
