Dear All,

This is probably a very basic question but:

I have plotted a map of the Barents Sea and surrounding coastline using:


Next, I imported a shapefile with depth contours for the sea:

contours<-read.shape("D://My Documents/BarentsSea.shp",dbf.data=T)

(This is in mercator projection).

Despite extensive searches of the help files and R site, I cannot find a
way to plot the contours onto the map.  Does anyone have any suggestions?

Thankyou for you help,
