I have just uploaded a package to CRAN called `gpclib' for clipping large and complex polygons. This package provides an R interface to Alan Murta's very fast General Polygon Clipper library (written in C), which has an optimized version of the Vatti algorithm. Not all features of Murta's library are implemented -- right now you can do intersections, differences, and unions. There

Hello. For building REmbeddedPostgres in Omegat project(http://www.omegahat.org/RSPostgres/) requiring PostgresSQL's libs, I've tried to build R1.6.1 on Cygwin following the instruction of http://www.stats.ox.ac.uk/pub/Rtools/ since full-spec PostgresSQL running on Windows can run only on Cygwin environment, However I've got following error messages. make -C front-ends Rpwd

Dear R-helpers, an rgl-ers in particular, what is the easiest way to plot a section of a plane in 3D, that is given by the xyz coordinates of the outline? Suppose I have a polygon - which I know for sure is a set of coordinates on the same plane. One method I found is to use surf.tri from the geometry package, and then plot the triangles with rgl.triangles. This method is not perfect though,

In Germany the Unemployment Agency uses a sectioning of the german map that is different from the usual Administrative Boundaries. Some demographic data are available in Administrative Boundaries only, some in Unemployment Boundaries only. I would like to generate estimates in one boundary system of data availabe in the other boundary system, and would appreciate advice concerning the following

Hi. Three years ago, I've read the question of availability of SOM library for R using Kohonen's SOM_PAK in this mailing-list. This answer was no availability. And no package dealing with SOM in CRAN. Is this situation same? Could you tell me availability this library? Best Regards.

R-devel, I'm interested in looking at some examples of existing R packages that rely heavily on S4 classes to get a feel for varying styles and package organization techniques. Could you recommend any packages that might serve as a good starting point? Thanks in advance, Jeff

Dear R-helpers, thanks for yesterday's speeding-up tip. Here is my next query: I have lots of polygons (not necessarily convex ones, and they never have holes) given by x,y coordinates. I want to get the polygon that is the union of these polygons. This is my current method, but I am hoping there is a faster method (up to thousands of polygons, each with ca. 40 xy points). Example:

This is the first time that I have tried to update packages with a tinkered around with .Rprofile. I start R with R --vanilla and it does not load my .Rprofile, but when I issue the command update.packages() R downloads the packages as expected, but then seems to load .Rprofile before compiling the packages sources. What am I doing wrong? kindest regards, Stephen Sefick see- Session info

What is the simplest (namely: minimum number of libraries or conflicts) way to fill a polygon with a pattern? For example, suppose I have (in a graphic file, like a jpeg) the drawing of an "X". Then I fill a polygon (like a triangle) with this pattern, and get something like: X XXX XXXXX XXXXXXX (where the border "X"s could be truncated). I searched the rimage

I have a list of polygons generated by the contourLines() command (each object of the list is a list in itself with two objects: a vector of x values, and a vector of y values for each vertex). I wish to convert that list into a gpc.poly object of multiple contours. How do I do this? gpclib apparently has no method of coercing lists into the gpc.poly object type. As well, when I have a

I am running R on Ubuntu Heron. I recently updated to R 2.8.0 from the default (2.6) in the Ubuntu heron repository by adding deb http://cran.stat.sfu.ca/bin/linux/ubuntu hardy/ I updated all packages installed in /usr/lib/R/site-library and those in my home directory /home/duncan/R/i486-pc-linux-gnu-library/2.6 without obvious issues. I installed adehabitat and gpclib, which should be good
