For a single function of one variable you can use uniroot. Use ?uniroot in R to find out more. You can also try general purpose optimisation algorithms such as optim/nlm, but they don't always find a solution and they are not very efficient for systems of equations. I am working on a package for solving (dense) non linear systems of equations using Broyden/Newton and global search methods. But it isn't ready yet and it will take time ...
