Hey,
    Is there any function plotting several "implicit functions"
(F(x,y)=0) on the same fig.     Is there anyone who has an example code of how
to do this?
    The contour3d function in the misc3d package only work with the  functions
with three dimensions.
    Thanks a lot.
    Many thanks for your help.

contour() will do it.  Use add=TRUE to add extra functions.

P.S. Please use a more informative subject line!

Some sample data would be useful.  If you want to add more lines to a
plot, the use 'lines'

plot(fun1,....)
lines(fun2, ....
lines(fun3, ....
