Unexpected parameter problem using rsaga.geoprocessor() {RSAGA}
Hello,
I discovered SAGA, an interesting free GIS, a few days ago and now, I
would like to use it from within R 2.6.2 using the RSAGA package. I read
the documentation for this package and thought that I understood it
correctly for trying to call some of the SAGA modules. For getting the
information on the usage of and arguments required by the SAGA command

Problems of exporting raster to ArcGIS
Hello:
I am using R raster package to replace ArcGIS when processing multiple shp files. However, when I export R raster back to ArcGIS, it couldn't recognize R raster file correctly. For example, I used {raster} package and got a RasterLayer as followed.
class : RasterLayer
dimensions : 8280, 18480, 153014400 (nrow, ncol, ncell)
resolution : 0.008333334, 0.008333334 (x, y)

why variations in accuracy between R to ARCGIS for the same point reprojection?
Hi everyone,
I wonder if anyone knows the reason why the outputs of the same
reprojection in r and arcgis are different?. The magnitude of the
change can be up to 40 km in the poles.
Basically, I have a database of points equally separated by one degree
over the globe.
In ARCGIS, I am projecting the data in GCS-WGS-1984 and then
reprojected it to Berhmann to ensure equal area

not getting anything back.

ArcGIS?
there is more than RArcInfo and Shapefile which can

nndist R vs. ArcGIS
Can anyone tell me why I would get different average nearest neighbor values
for the same set of coordinates between ArcGIS 10 and R? Sometimes the
difference in distance is over 1.3 km.

Mysterious issues with reading text files from R in ArcGIS and Excel

Reading an ArcGIS raster file
Dear members,
How can I read and plot an ArcGIS raster file into R ? The file has extension .aux and contains floating point bathymetry data. The purpose is to create a spatial model in R that uses ArcGIS map data. I have managed to read and plot various shape files into my R project, but I am stuck with this now. I am new to this list and also to R, so any help would be much appreciated.

produce a map in ARCGIS from a GAM output
Hi,
I am trying to predict the habitat suitability of lobster with GAMs. I need to produce a map in ArcGis of the predicted densities. I did some search and the function predict.gam seems to do the job.
Is this the right way to do it? when you apply the function you get the predicted values (different from your input data points) but I do not understand what is the procedure with the spatial

writing polygons/segments to shapefiles (.shp) or other ArCGIS compatible file
I am not sure a previous e-mail reached the list (no mail aknowledgement from R-boundle etc.). The question was how to write polygon
or segment coordinates into a shapefile set or any other ArcGIS supported format. The library shapefiles seems to do something but
the documentation is a bit beyond of my mind.... and I cannot get the meaning of the functions write**** and its application to the

who can tell me the reason why it is different on calculating Moran's I using ARCGIS, Geoda and R?
The attachment is my dataset:
1.ccc.shp (the original data)
2.ccc.gwt, which is computed by Geoda;
Introduction to the variables in my data:
ID: key variable;
N_LATITUDE: latitude measured by GPS;
E_LONGITUD: longitude measured by GPS;
LIVES: attribute data
I get the different result of Moran's between ARCGIS and Geoda, R, why?

rgdal: Convert ESRI ArcGis geo database (gdb directory) to geojson, or shapefile map
Hello,
I have an ESRI ArGis geo database directory which I would like to convert
to geojson or a shape file (or anything else that I can read into R).
Unfortunately that does not work out of the box with rgdal, because it does
not come with the fileGDB or openfileGDB driver.
I could successfully install gdal and the fileGDB driver/extension, but it
seems that i can use gdal only to convert the

R Output and ArcGIS
Dear all,
I've been using R on a Mac to process some data for export to ArcMap GIS (which only runs on Windows). ArcMap seems to require tab-delimited data (my data are in 3 columns), so I've been using the sep="\t" argument. However, this resulted in strange end-of-line characters when displayed on a PC. I looked in the write.table help file to find that eol="\r\n"

Reading a TIFF file
Dear all, I have been trying to speed up a process we have been done in ArcGIS. We have to read a single layer TIFF (monochrome image) in . For this, I have used the "rtiff" package. After reading the TIFF file, I compared the raw values for each pixel that I have in ArcGIS to the ones obtained in R. In ArcGIS I have discrete values in the range 0..255, while in R I have continuous
