Hi Pablo,
sorry for a late answer again.
I am not sure what is the cause of slow execution of your code. I would either
have to look at an example, or you can run it with Rprof(). Then you can see
the most time consuming functions, although I am not sure how it works with
JIT. If you send the
Dear All,
I have a problem with combining polygons and calculating their area.
In the following I try to provide a description of the problem:
I have a simple raster (created with R-package: raster). Using the function
rasterToPolygons I get polygons of all raster cells that contain the

Alex,
Do you need to create polygons? You can do things like:
m - clump(r)
freq(m)
But if you insist on polygons:
m - clump(r)
p - rasterToPolygons(m, dissolve=TRUE)

It's not highly structured, but it present information in a different way.
These are two I'm aware of (I've made the last one).
