I am new to mapping with R, and I would like to use the point.in.polygon function from the sp package, but I am unsure of how to get my data in the correct format for the function. The generic form of the function is as follows:
point.in.polygon(point.x, point.y, pol.x, pol.y, mode.checked=FALSE) I have no problem with the point.x and point.y inputs. I have a list of gps longitudes and latitudes that will go in fine. My problem is with the pol.x and pol.y input. My polygon is currently in the form of a SpatialPolygonsDataFrame created by inputting shp files with the rgdal package. How do I get a numerical array of the x- and y-coordinates from my polygon that will go into the point.in.polygon function? -- View this message in context: http://r.789695.n4.nabble.com/point-in-polygon-help-tp4667645.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
