[R] nonlinear modeling with rational functions?

Rational functions (ratios of polynomials) often provide good
approximations to many functions. Does anyone know of any literature on
nonlinear modeling with rational functions, sequential estimation,
diagnostics, etc.? I know I can do it with "nls" and other nonlinear
regression functions, but I'm wondering what literature might exist
discussing how a search for an appropriate rational approximation?
