comment How to open a Shapefile in R?
@user4050, hard to know without seeing your code. I assume there is a .prj file in the same directory? and that you used the encoding = "ESRI Shapefile" value to make sure rgdal knows it is a shapefile?

comment Proper way to rbind SpatialPolygonsDataFrames with identical polygon IDs?
Really just three lines of code for the function and one to apply it pre-rbind, but it does take some time to process for your problem. I have always found the handling of the ID in SPDF's to be a problem (any time I load something with rgdal for example), but Roger Bivand always seems to be able to make them behave so I have just assumed it is my own shortcoming. I like the idea of a patch, but wonder if accessing those slots would cause complications for other things in sp.
