This function is separable.
If calculating by hand with bounds a -0 and b - 1 i got the result:
theta / kappa * ( 1 + exp( - kappa) / kappa - 1 / kappa)
by putting
theta - 0.1
kappa -0.3

abind() (from package 'abind') can take a list of arrays as its first argument,
so in general, no need for do.call() with abind().
As another poster pointed out, simplify2array() can also be used; while abind()
gives more options regarding which dimension is created and how dimension names

Hello,
As for the first question, you can do something like

Timefram-1

As for the second question, the answer is yes, there is a print()
