Error: $ operator is invalid for atomic vectors about msgarch HOT 2 OPEN

I'm finding the same problem! Did you find a work around?

from msgarch.

The same here.
The problem does not seem to be related to the format of the provided data to FitML() but rather to the data content.

I have lots of datasets to reproduce this problem with if someone is interested.

It looks like the problem is in line 131 of ../Package/R/FitML.R:

129 optimizer <- ctr$OptimFUN(vPw, f_nll, spec, data_, ctr$do.plm)
130
131 llk <- -optimizer$value

I suspect that the optimizer in some cases (depending on the actual data?) is returning an atomic vector and hence the error message "Error in optimizer$value : $ operator is invalid for atomic vectors".
