## Use buildmer to fit big generalized additive models using gamm from package mgcv

### Description

Use buildmer to fit big generalized additive models using gamm from package mgcv

### Usage

buildgamm(
formula,
data = NULL,
family = gaussian(),
buildmerControl = buildmerControl()
)


### Arguments

 formula See the general documentation under buildmer-package data See the general documentation under buildmer-package family See the general documentation under buildmer-package buildmerControl Control arguments for buildmer — see the general documentation under buildmerControl

### Details

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 in the args list in buildmerControl. Note that buildgamm will merely pass this through; no term reordering or stepwise elimination is done on a user-provided random argument.
