Additional options to be passed to |
The fixed and random effects are to be passed as a single formula in lme4
format. This is internally split up into the appropriate fixed
and random
parts.
Only a single grouping factor is allowed. The random-effect covariance matrix is always unstructured. If you want to use pdMat
covariance structures, you must (a) not specify any lme4
random-effects term in the formula, and (b) specify your own custom random
argument as part of the ...
argument. Note that buildgamm
will merely pass this through; no term reordering or stepwise elimination is done on a user-provided random
argument.
