Plotting shapefiles on existing maps
...but:
I have plotted a map of the Barents Sea and surrounding coastline using:
map('worldHires',ylim=c(50,85),xlim=c(5,65),fill=T,resolution=0)
map.axes()
map.scale(x=30,metric=T)
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,
Lillian.

Converting shapefiles to use in contour plots
Dear R-users,
I have imported a shapefile with depth contours for a sea:
depths<-read.shape("D://My Documents/BarentsSea.shp",dbf.data=T)
(This is in mercator projection)
**Is there a way to convert this shapefile into a format that it may be
plotted on a contour plot?**
I wish to add these contours onto a map (already coded using 'maps'
package) to map the sea contours with surrounding coastlines and...
