convergence problem gamm / lme
Hope one of you could help with the following question/problem:
We would like to explain the spatial
distribution of juvenile fish. We have 2135 records, from 75 vessels
(code_tripnr) and 7 to 39 observations for each vessel, hence the random effect
for code_tripnr. The offset (‘offsetter’) accounts for the haul duration and
sub sampling factor. There are no extreme outliers in lat/lon. The model we try
to fit is:

t.test in a loop

I've used the get(paste()) idea as i was told previously that the use of the
eval should try and be avoided.
I've run a single syntax to check that my systax is correct and works
