hi,
i've compiled rgdal on mac osx 10.4.7
using this powerfool packages at this site :
look for "gdal-framework"
you can compile rgdal from command line , you must specify where is
gdal-config
(R CMD install --with-gdal-config=/path-to-gdal-config /path/to/-
rgdal.tar.gz)
Massimo.

It might not handle the amount of data you have, but,
if your tables are normal dataframes, it would do the
job with a smaller dataset. It doesn't work with
Spatial*DataFrames (yet?).

One possibility is that the size of the GDAL data type is not the same
as the size of the R data type. This will definitely cause problems as
allocation is done by R and the pointer is cast to void when passed to
GDAL. My original C++ code simply assumes that both are 32-bit (or at
least equivalent

Thanks very much for your detailed
After sending my last post, detailing my system setup with a working
R/GDAL/rgdal installation on a Mac, I played a bit more and came
across a glitch when I tried example(readGDAL) on the fresh build.
It gets through translating the data set and the image command, but
then on summary() I get

Hi Debs.
I do not think any of the statistical methods implemented
in DCluster is suitable for the analysis of point
processes in their current state. Some of them could
be used with ppoint proesses (GAM, Spatial Scan), but
the current implementation of the methods assumes
areal data.
