Dear all,
I understand that plot.Map (the default method for plotting shape objects) is
deprecated, however I have not found a working method converting my shape file
into either a polylist or sp class.
I tried the following
p2roads <- read.shape("sf.shp")
SF.map <- Map2poly(p2roads)
where sf.shp is a shape object of the San Francisco street map, and get the
following error message:
Error in Map2poly(p2roads) : maptype not poly
Are there differences between shape files ? Which other way could I try to
convert my shape object so that plot.Spatial will work ?
Thanks !
Markus
