Hello,
I had the same problem in the past and so I developped a function that
allow to convert directly a raster to a SpatialPolygonsDataFrame.
The function ('polygonize') is available in a small package I wrote :

The package is written in French
Dear list,
I am trying to characterize different tillage patterns of agricultural
fields using variogram analysis for microwave remote sensing. Basis for
the analysis is a high resolution DSM with a 2x2 mm^2 resolution and a
size of 1x6 m^2 (see pdf at
Hi Tom,
thanks for the answer, but I am explicit interested in the direction
perpendicular to the row, due to imaging direction of the radar
satellite. In addition, we also acquired DSMs in parallel to the rows,
which as you mentioned do not show these behaviour. However, an
anisotropic

No, simply run lm() on the same

Hi,
And will contiguous raster cells have the same value, as Arnaud expected?
Wanted, I think, rather than expected. In a word, I have no idea. :-)
I don't grok rasters, and frankly the desideratum makes little
sense to me.

Having thought about it a bit more, I *may* have understood what the problem
is, and how to proceed. At least in part.
If I am understanding things correctly, what needs
