set_simcodes function

helper function to modify simulation settings for random effects

This modifies the TMB object in place (beware!) Ultimately this will allow terms to be a vector of term names, with a matching val vector to specify the behaviour for each term

set_simcodes(g, val = "zero", terms = "ALL")

Arguments

• g: a TMB object
• val: a legal setting for sim codes ("zero", "random", or "fix")
• terms: which terms to apply this to
