Tried to use a dynamic library that wasn't there: >> useDynLib(randomepi) but you never built a randomepi.so. You built randomepi.o, but that is an object file not a dynamic library. It was eventually linked into Nepidemic.so, which is the thing that you do want to useDynLib() on. -pd (Incidentally, watch your casing, you use "Nepidemic" and "NEpidemic" every other time. Sooner or later you'll find yourself in a situation where the case actually matters and gives you a mysterious malfunction.) > -Vineetha > > On Thu, Jun 16, 2016 at 2:48 PM, Eduardo M. A.
