Re: [R-sig-Geo] Subset SpatialGridDataFrame by retrieving xy coordinates from bounding box
This can be easily done in the "spatstat" package if you convert the object of interest to a spatial point pattern (object of class "ppp"). See the vignette "shapefiles" for some guidance on how to do the conversion. cheers, Rolf Turner On 16/10/12 13:54, Nathalie Morin wrote: Hello !

Re: [R-sig-Geo] spml, spfeml and tolerance level
After some exploration and a hint from the package administrator, the quickest way I found to avoid this problem (without having to customize functions within the package) was setting: .Machine$double.eps <- .Machine$double.eps^2 Just in case anyone faces this. cheers.

[R-sig-Geo] problem creating psp
Hello Everyone,
I am currently trying to complete the simple task of converting a
SpatialLinesDataFrame to PSP so that I can do kernel density estimation on
the line pattern (density.psp). When I do this, however, I get an error
that does not allow me to proceed. Here is the code I am using (along with
the error):

Error in as.data.frame.vector(x, ..., nm = nm) :
formal argument "nm" matched by multiple actual arguments
I have not worked with line data much so any assistance would be greatly
appreciated.

Re: [R-sig-Geo] rgeos: gOverlaps not working properly?
‘gOverlaps’ returns TRUE when the geometries share some but not all interior points, and the intersection has the same dimension as the geometries themselves. Hence gOverlaps(A,A) == FALSE due to that 'but not all' part of the documentation. Barry ___ R-sig-Geo mailing list R-sig-Geo@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo

[R-sig-Geo] kernel2d -> raster/grid
Hi, how can I convert kernel2d estimation to a raster in order to use it as a mapserver layer? I saw maptools can save kernel2d to contour to shape file with ContourLines2SLDF. Any hints?
