[R-sig-Geo] Bivand book chapter 2 Auckland example

[rotundo]

Hello Mathias,

Thanks a lot for your response. I tried what you suggested but it didn´t
work.

I don´t think the error is in the file path, since I am using R studio, and
the file auckland_mapgen.dat is already imported to the workspace. So,
after loading the file, I run three different  codes, but still have the
same error message:

library(maps)
library(maptools)

#Example Page 41 as in the book
llCRS <- CRS("+proj=longlat +ellps=WGS84")
auck_shore <- MapGen2SL("auckland_mapgen.dat", llCRS)

# without .dat
llCRS <- CRS("+proj=longlat +ellps=WGS84")
auck_shore <- MapGen2SL("auckland_mapgen", llCRS)

# Creating another data set
llCRS <- CRS("+proj=longlat +ellps=WGS84")
auck_data <-auckland_mapgen
auck_shore <- MapGen2SL("auck_data", llCRS)

I attached a print screen of the R workplace so you can see what I did.

Thanks a lot for your help.

Jose
