Re: [R] Error opening SHP file

Let me just make this case simple and quick to address what I need. Giving a data-file that includes tow columns: zip5 and population. How do I put pop (colored with different segments) by zips (with boundary) on the USA map with R? Amoy On Friday, January 22, 2016 12:45 PM, David

Re: [R] Error opening SHP file

We can duplicate the error by giving a path to a non-existent shapefile, which is probably the original problem: > require(maptools) Loading required package: maptools Loading required package: sp Checking rgeos availability: TRUE > foo=readShapeSpatial("fnord.shp") Error in getinfo.shape(fn) :

Re: [R] Error opening SHP file

Hi Amoy, Another mystery question. I should have pursued parapsychology. That error statement is usually followed by one noting that the file specified cannot be found. Today's guess is that the R working directory: getwd() did not have a "maps" directory below it. Jim On Fri, Jan 22, 2016 at

Re: [R] Error opening SHP file

Agreed with the others. After finding that shapefile and getting it to work you are definitely not in the proper working directory. On Thu, Jan 21, 2016 at 8:40 PM, David Winsemius wrote: > >> On Jan 21, 2016, at 4:39 PM, Amoy Yang via R-help >>
