Re: [R-sig-Geo] Merging regions in a map & plotting values

You really don't want to bind the data to the regions. My example showed how to use a separate data frame. I won't have time to provide an even simpler example until the weekend and (I realize this is list anathema) this would work alot better as a Stack Overflow question. On Fri, Jan 22, 2016 at

Hi Bob, Still getting the memory error to do with memory after merging the data to plot points as per your suggestions. What could I be doing wrong is is there a way out to fix this? Thanks dat_merge =merge(regions,orf_data,by="Region",duplicateGeoms=TRUE) eng_map <- fortify(regions, region="Regio

I can verify that geocoding street addresses in the US with the PostGIS TIGER geocoder works, and that you can use RPostgreSQL from R to issue the geocoding commands. I'm running Linux Mint 17.1, and to get the geocoder working, I simply went through the steps as outlined in PostGIS in Action,

Dear Christopher, Have a look at the rgeos and spgrass6 packages. rgeos provides several GIS operations. spgrass6 allows to move data from R to GRASS GIS (and vice versa). You can run GRASS operations from within R. Best regards, Thierry ir. Thierry Onkelinx Instituut voor natuur- en bosonderzo

Hello. I'm a longtime R and R-help user, and recent listener on R-sig-geo. First post here. I use R on both Win 7 and Linux Mint. Is there a way to geocode street addresses in the US within R on my local machine, that is, without transmitting the addresses to any web-based service? I have about 2

If this can be of any help, I spend a lot of time tiling and working with large rasters in R (usually a combination of R, raster and sp packages + GDAL utils and SAGA GIS) so eventually I have made my own tiling functions: http://gsif.r-forge.r-project.org/tile.html The source code is at:
