[R] 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 answers
to my previous question (thankyou to everyone for that) seem to suggest
that using contour plot is the way to go.

Thankyou again,
