I have shapefiles for the state climatic divisions for the United States and read.shape brings them in wonderfully. Now I wish to run through a list of several thousand observation sites to find out in which division each is located. I figure that I can compute the winding number for each site and be done. However a search doesn't find any references and I can't find a winding number function among the map/tools/stats. I have the code for an efficient C++ but was expecting that it would already be implemented as an R function
Since I haven't used the map/tools/stats collection before, I suspect I'm overlooking the function and would be thankful for a pointer.
