Loading Rasters in Revolution R
I'll mention the problem you are describing is what I designed "rasterEngine" (part of the spatial.tools package) for. It will allow you to do parallel processing of rasters with arbitrarily complex functions applied to pixels or focal windows. Don't even need Revolution to use it, just good 'ol base R! --j

Sounds like a question for Revolution... Best, Ista On Wed, Oct 22, 2014 at 4:29 PM, Jefferson Ferreira-Ferreira <jecogeo at gmail.com> wrote:
Hi all, I'm wondering how to load rasters as xdf files using rxImport. I have a big raster with 9 layers/bands and I need to do perform a logistic regression for each pixel throughout bands. So It's a huge processing, and why I'm testing Revolution R Enterprise. However I don't know how to import as xdf files to perform parallel processing inside it. Almost blogs and tutorials deals with ordinary csv files. Could anybody give me any guidance? Regards -- *Jefferson Ferreira-Ferreira* Ge?grafo ?
