Wierd nlm behaviour in 2.10.1 and 2.12.0 [Sec=Unclassified]
Hi all,
When upgrading to 2.11.1 recently I noticed different results being produced by my code.
After much digging I have finally narrowed it to a call to nlm().
This can be replicated by:
FixedRemovals<-1836180125888
AbStageInitial<-2223033830403
Rates<- 0.3102445

{(Loss-(rootM/(rootM+OtherM)*
(1-exp(-(rootM+OtherM)))*
Abund))^2}
,0.001,print.level=0,fscale=0, gradtol=1E-10, stepmax = 100.0
,Loss=FixedRemovals
,Abund=AbStag...
