Robert, thank you very much! I believe this sets me on the right path. 2 issues I'm looking into: 1) I do receive an S4 error after the as.matrix(x) step: > as.matrix(x) /Error in as.vector(data) : no method for coercing this S4 class to a vector/ 2) Perhaps related, I'm not sure if I'm losin

Diann, A good way to start would have been to provide a function that works for one cell, I had to do some guessing now, but I think the below should point into the direction of a solution. library(raster) library(rgdal) library(mc2d) #load package # you can directly read the ArcGRID files using

Hi all, I hope you forgive me for this cross-post. I requested help a few days ago on the general R-help board but haven't received a response. I think that a solution can most likely be answered by someone familiar with working with large spatial datasets. I have raster datasets exported from Ar
