R help - Jan 2012 - analytical solution of partial differential equation

i am trying to solve a partial differential equation analytically(PDE) in R .
i have found some functions that do the stuff numerically. But that will not
meet my purpose. is there any function to solve PDE  analytically. please
help.

  With extremely limited exceptions (D(), deriv()), R doesn't do
analytical solutions.  There is an interface to Yacas.  You might
try Mathematica, or Sage (search if you are looking for a free solution.
Good luck, though: solving anything but the simplest PDEs analytically
is very challenging ...
