Arguments
fixed
a formula of the form response ~ terms where
response is an expression for the response and terms
are one or more terms that define the fixed-effects.
random
a named list of one-sided formulas. The names in the
list evaluate to the grouping factors and the right-hand side of the
formula is an expression for a pdMat object that itself
contains a formula. The order of the components of
data
a data.frame or model.frame in which the
fixed and random arguments can be evaluated.
weights
a numeric vector of prior case weights for the
observations. Defaults to equal weights.
REML
a logical value: if TRUE the REML
criterion will be used for parameter estimation, otherwise the ML
criterion will be used.
nextraCols
an integer giving the number of extra columns
to be added to the stored matrices.
analyticHessian
a ilogical value: if TRUE the
analytic Hessian of the objective can be calculated using the
