I would guess -- we don't have a reproducible code -- that you have an
undefined function value. Since nmkb is entirely in R to my knowledge,
you could simply take the source code and modify it to display the
elements in the test that cause the trouble. Then load the source rather
than using library(dfoptim).
Alternatively, add to your objective function some code to display the
parameters before evaluation and the resulting value that is returned.
Messy but pretty effective to reveal if and where the function is giving
trouble.

Hallo together,
I am trying to use the nmkb() optimizer and I have problems using the
function, as it causes the following error message
Fehler (error)* in while (nf < maxfeval & restarts < restarts.max & dist >
ftol & :
Fehlender Wert (missing value)* , wo (where)* TRUE/FALSE n?tig ist (is
required)*
*translation
Do I need to adjust the control ?
my.optpar3<-nmkb(par=par.start,fn=my.loglike.normal,lower=constLo,upper=999,
control=list(restarts.max=9))
If you need more info, please let me know.
I would appreciate some help, thank you very much.
Best,
Marcial
