[R-sig-Geo] problem with OpenStreetMap

[christiaan pauw]

Hi Everbody

I read this blog about the new OpenStreetMap package
(http://www.r-bloggers.com/plot-maps-like-a-boss/), downloaded the
package and tried out the example.

The first example is:

library(OpenStreetMap)
library(rgdal)
map <- openmap(c(70,-179), c(-70,179))
plot(map)

It looked simple enough. However, this resulted in an error which
appears to be related to the fact that my R version is 2.14.0 and the
package ‘OpenStreetMap’ was built under R version 2.14.1  (see below
together with sessionInfo())

Is this correct or is it perhaps something else.

regards
Christiaan
