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:

Dear Janka,
I can't answer your ggplot questions as I don't really use it much however I
did spot something in your code that will cause problems.
You used a merge to combine data between a dataframe and an SPDF:
ValueMapDf - merge(nuts, Value, by.x=NUTS_ID, by.y=NUTS_ID)
I've forgotten the
of variation.
What is if that controls the degree of smoothing for want of a better term!
Many thanks,
