Hi R-helpers

I would like to plot some planes which are perpendicular to the x-y

plane, such as x=y. Is there a way to do this in wireframe? I realize

that I am not plotting a function of x, y since there are infinite

number of z's that satisfy the above relation.... Hmm...

Somewhat related, I would also like to plot a line in 3 d space...

Finally, if you are feeling really brave, I am interested in doing all

of this based on sums generating vectors (I know there is a linear

algebra term for this) -- ie generate the plane based on c_1*v_1 +

c_2*v_2 for c_1 and c_2 in reals.

Thanks again to all you helpful folks!

W
