This sounds promising.

Also remember that user-defined macros are possible, so even if you need
a lot of contortions to enter the code, you can simplify it at the Rd level.

I know that equations are rendered beautifully in the pdf manuals, but I suspect the majority of users primarily look at the html help files when using R. While I am comfortable reading something like "B_x(a,b) = integral_0^x t^(a-1) (1-t)^(b-1) dt", it would definitely be nicer if this was shown as a 'proper' equation.
