[R-sig-eco] Quantifying widths of polygons

2015-09-30 Thread Alexander Shenkin
Hello all, I am working with data on tree crowns, and this data describes points (verticies) around the polyhedron of the crown volume (think of the crown as a single volume with vertices and faces). I can calculate maximum z distance between any 2 points (maximum depth) and maximum x/y dist

Re: [R-sig-eco] Good Book for learning R

2008-05-06 Thread Alexander Shenkin
I will second Dan's sentiment here: I haven't found a single source which comprehensively lays out the programming framework for R (though I've never seen The R Book). I ended up learning (and still am learning) how to program R in a relatively piecemeal manner. Some of the references which c
