    MW> It appears that phyper hangs for insanely large x, such as the call

Yes.  I think it only happens for  (x, 0,0,0)  though.

    MW> Adding something like this after the tail swap seems to cure that.

    MW> if (x >= NR)
    MW>    return R_DT_1;

yes, and that also cures  phyper(1,0,0,0)  which gave NaN
instead of 1.
Is going to be fixed for R-devel and R-patched.

Thank you, Matt!
