[R-sig-Geo] readOGR problem in Windows

[James Rooney]

Dear List,

I have some code I have developed on a Mac that I'm trying to transfer onto a higher spec windows 8.1 machine and I am running into a problem with the readOGR function in rgdal.

My code is below. This works fine under Mac, but under windows readOGR gives me the error:
"Error in ogrInfo(dsn = dsn, layer = layer, encoding = encoding, use_iconv = use_iconv, :
Cannot open file "

The rgdal version on the Mac is rgdal_0.8-16
whilst on Win 8.1 is rgdal 0.9-1

The preceding read.csv statement works just fine.
Any ideas anyone ?
Thanks,
James


Code:

library(rgdal)
library(rgeos)
library(maptools)
library(RColorBrewer)
library(classInt)
library(ggplot2)
library(INLA)
