[R] solving equation system

I want to solve some two dimensional equation system with R. Some systems are not solvable analytically.  

Here is an example:  

(I) 1/n*sum{from_i=1_to_n}(Xi) = ln lambda + digamma(c)

(II) mean(X) = x / lambda

I want to find lambda and c,  

which R-function could do that task?
