hi R-users: I have some data related with geographical information. I wonder how to plot some data (in contour,shaded or scatter) on a map. Could anyone tell me which package or reference or examples I can learn ? thank you . -- TANG Jie Email: totangjie@gmail.com [[alternative HTML version deleted]]
