Dear R help,
Suppose I have a dataframe with three columns named p, v and C.
Here C is a function of both p and v. I can plot the surface C(p,v) using the
package lattice using the function wireframe.
Now if I have another dataframe - with 2 columns named p_ind and v_ind and pind
is a function of v_ind.
I would like to overlay the plot of the curve p_ind, v_ind and C(p_ind, v_ind)
onto my previous plot.
I haven't found a way to do this.
Please help.
Raff.
