Subject: package: maps and spatstat question
I would like to use the output from the map function
in the package maps for use in, say, the spatstat
package. I don't quite understand the coordinates
for the border of the state:
Example:
library(maps)
iowa<-map("region","iowa)
x<-iowa$x
y<-iowa$y
There are NA's and duplicated coordinates.
What would I need to do to use this in the
spatstat owin command?
owin(poly= ?)
Thank you.
