[R-SIG-Finance] Symbolic computation in R

I'm a R-newbie and not very familiar with the concepts of numeric and 
symbolic programming environments.
As an undergraduate student i have to compute a lot of symbolic stuff 
like partial derivatives or integrals.
For that purpose Maple or Mathematica are quite good tools, but i want 
to stick to R.
The following functions seem to be the ones to get symbolic derivatives:
D (expr, name)
deriv(expr, ...)
deriv3(expr, ...)
But i could'nt find any other functions for symbolic computation in R.
So here are my questions:

Is there a function to perform a symbolic integration?

Is there a way to solve an expresion like 2*x=y for x symbolically?
