Hello everyone. The hypergeo() function of the Davies package has some functionality for the F^2_1 case [it's been a long time; I may be confusing my subscripts and superscripts]. But this and other cases are covered by the gsl package, which is a wrapper for the GSL library (probably this is a much better option). Going back to hypergeo(), it seems relatively easy to add any specific number of extra superscript or subscript parameters. But a truly generalized version (which would need to take a vector of superscript parameters and a vector of subscript parameters) isn't so easy. It's on my List Of Things To Do, but I'm afraid it's not near the top.
