Hello,

I am trying to perform several spatial analysis on R, based on polygon
lists. My data come from ArcGIS, being in shape format. I would like to
create a polygon list from this file. Apparently, R reads properly the file
by using the function "read.shapefile", however when I try the function
"plot" on this object, the program does not recognize which are the X and Y
coordinates (which -by the way- are in decimal degree units). Should I use
any specific sintaxis to indicate which columns are my coordinates? or
maybe I have to project my coordinates somehow?

Thank you very much indeed,
