GpSHP2gnu: Work with shapefiles
In Rgnuplot: R Interface for Gnuplot

Description Usage Arguments Value Author(s) See Also

GpSHP2gnu given a shapefile (SHP) with full path and the shapefile layer name, the coordinates are saved to a text file readable by gnuplot

GpresampleDEM resamples DEM data, similarly to what GIS applications do

GpboxXY returns the box (coordinates) around a location, from a shapefile

GpmapPNG2lines draws "squarish" coastlines given a gridded map from a PNG image

Gpmatrix2PNG saves a matrix with a mask of a map to a PNG file

GpplotMap plots a map with vector and raster overlays
