There are 17 long double functions and some complex functions missing, but only a handful of those are of general interest. The reason I ask is that if R is just looking for a few missing functions that are already mostly implemented, then the best solution is probably to finish that work. But if it's expecting us to have something arcane like long double Bessel functions of the first kind, then we need to pursue a workaround in the short term.Received on Tue Jul 10 2012 - 13:11:23 UTC
