checkConv

typically the "derivs" attribute of <code>optimizeLmer()</code>; with
 "gradients" and possibly "Hessian" component

derivs

coefs

list of lists, each with <code>action</code> character strings specifying
 what should happen when a check triggers, and <code>tol</code> numerical tolerances,
 as is the result of <code><a rd-options="" href="/link/lmerControl?package=lme4&version=1.1-21" data-mini-rdoc="lme4::lmerControl">lmerControl</a>()$checkConv</code>.

ctrl

vector of lower bounds for random-effects parameters only
 (length is taken to determine number of RE parameters)

lbound

enable debugging output, useful if some checks are on 
 "ignore", but would "trigger"

Primarily internal code for checking optimization convergence,
 see <a rd-options="" href="/link/convergence?package=lme4&version=1.1-21" data-mini-rdoc="lme4::convergence">convergence</a> for a more detailed discussion.

Fit linear and generalized linear mixed-effects models.
The models and their components are represented using S4 classes and
methods.  The core computational algorithms are implemented using the
'Eigen' C++ library for numerical linear algebra and 'RcppEigen' "glue".
