[R] plot multivariate function with known coefficient.

Dear R users -- I have a simple question that I cannot find the answers in the archive email: how to plot a multivariate function if I know the coefficients already? For instance, if I like to plot a 3D fig of Pi against X and Y with the function Pi = a0 + a1X + a2Y, where a0, a1 & a2 are known.
