Thanks, I think

family=mvn(d=3)

​in mgcv gam() works!

Also search on "multiresponse GAM" or similar at rseek.org<http://rseek.org>. This brought up what looked to me like useful hits.
And of course, don't forget Mama Google.

Hello,

I am modelling the diet of Nile perch through time. I have 3 diet classes as
my response variables; fish 1, fish 2, and invertebrates.

The response variables are correlated, declines in invert consumption ~
increase in fish consumption. Any advice on how to handle this would be
appreciated. I would like to use GAMs as my time series shows fluctuations
that could only be fit by high order polynomials if I were to use a linear
model, but open to suggestions.

Thank you for your time.

P.s. I will be comparing the fit of the time series GAM with a model based
on other predictors, with a training and validation split for my data.
