Hello,

I'm a beginner in R and in spatial analysis. I learn it with the book
"Applied spatial analysis with R". I have a problem with some example that
explains how to write script for making polygons (chapter 2.6, page 41).

You can see what I wrote and what the response is: there is a problem of
connection. Can someone help me?

 

llCRS<-CRS("+proj=longlat+ellps=WGS84")

> auck_shore<-MapGen2SL("auckland_mapgen.dat",llCRS)

Error in file(file, "r") : cannot open the connection

In addition: Warning message:

In file(file, "r") :

  cannot open file 'auckland_mapgen.dat': No such file or directory
