I am getting an error, that I have no idea what to do about, from glmmTMB():
library(glmmTMB)
fmla <- cbind(Dead, Alive) ~ (Trt + 0)/Dose + (Dose | Rep)
X <- dget("X.txt")
fit <- glmmTMB(fmla, data = X, family = betabinomial(link = "cloglog"),
dispformula = ~1)
> Error in optimHess(par.fixed, obj$fn, obj$gr) :
> gradient in optim evaluated to length 1 not 16
> In addition: There were 16 warnings (use warnings() to see them)
The warnings are all repetitions of
> 1: In nlminb(start = par, objective = fn, gradient = gr, ... :
> NA/NaN function evaluation
The error sounds to me like something is amiss in the code.
Can anyone confirm/deny/suggest what I might do to get this call to
glmmTMB() to run?
Thanks.
cheers,
Rolf Turner
P.S. The data set is attached.
