Hello, I want to expose a problem I am now facing with the gdistance package and the geoCorrection() function.
I have a code I haven't been using since March, and now, after updating R to 2.15.2 and the package gdistance to 1.1-3 from 1.1-2, the geoCorrection() function doesn't work. It simply runs forever without giving any result. My code is fine, as I tested it with my old computer still running R 2.15.0 and gdistance 1.1-2 and it does the task in 15 seconds. The problem is really with the 1.1-3 version of gdistance. ## here a simple example of my code. ## download le Rdata: https://www.dropbox.com/s/mo51vgft3fsmm5y/transi.RDATA load("transi.Rdata") library(gdistance) transi <- transition(ras,transitionFunction=max, directions=8,symm=T) transi <- geoCorrection(transi) > sessionInfo() R version 2.15.2 (2012-10-26) Platform: i386-w64-mingw32/i386 (32-bit) locale: [1] LC_COLLATE=French_Canada.1252 LC_CTYPE=French_Canada.1252 [3] LC_MONETARY=French_Canada.1252 LC_NUMERIC=C [5] LC_TIME=French_Canada.1252 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] gdistance_1.1-3 Matrix_1.0-9 lattice_0.20-10 igraph0_0.5.5-3 [5] raster_2.0-31 sp_1.0-2 loaded via a namespace (and not attached): [1] grid_2.15.2 tools_2.15.2 ########## I've tried it on win XP and windows 7, 32 and 64 bits, still the same problem. I would be happy if somebody could fix it. Thanks Bastien Ferland-Raymond, M.Sc. Stat., M.Sc. Biol.
