I have a quick question: It appears that in rgdal v0.7-12 (R version 2.15.1, OSX 10.6.8) writeOGR will not write a shapefile the the current directory. Is this correct? An earlier version of rgdal must have allowed this because I have a older script that used to work, but doesn't now. So, as an example, here is what I get today: > shape = readOGR('.', layer='S20_G75_V00_HAA...

Hello R Community, I have imported a dataset which contain X Y coordinates and would like to recreate a shape file after some data analysis. What i have done is to import some taxlot data and join them based on some criteria. I want to check to see how well the joining went by reviewing the results in GIS. A couple things. I cant seem to import a shape file correctly using the maptools

Hi, I am new to R and am a very basic user. I'm importing SHP files, adding plots of random locations within my polygon (these files have GPS data), and then want to save these plots (intact with added points) as KML files to look at in GoogleEarth (or possibly as SHP files which I can then convert into KML). This is as far as I've gotten (code below) and am lost as to next steps, Any
