Hello All, I want to draw a figure with filled contour in a irregular map.
But I found that the contours overlap the boundaries of the map, and also some regions in the map were not filled. I have following data: data1. A shapefile (i.e., a map with boundary, for example, the whole Australia map); data2. A text file with three columns: x, latitude; y,longitude;z,variable (e.g., rainfall); and use following R code: Map<-readShapeSpatial("data1") plot(Map) data2.li<-interp(data2$x,data2$y,data2$z) filled.contour(data2.li, color=topo.colors, add=TRUE) How can I limits the filled contours just inside the map? Thank very much for that!
