Description 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''.

... Spatial independence of all datasets was examined using the Mantel test of the ade4 package (Dray and Dufour, 2007). To test the effects, generalized linear mixed models (GLMMs), generalized linear models (GLMs), linear mixed models (LMMs) or linear models (LMs) or using the lme4 package (Bates et al., 2014) (Table 1) were performed depending on model distributions tested in the car package (Fox and Weisberg, 2017) (Table 1) and where applicable, plantation estate was included as random parameter (Fig. 1). Post hoc tests were conducted using the multcomp package (Bretz et al., 2008). ...
... The model results at the different test times were analysed using generalised linear mixed-effects regression models ("lme4" package in R, Bates et al., 2014). Models were constructed for null and overt pronouns separately, each time with interpretation (subject or non-subject) as the dependent variable, test time as a fixed factor, and intercepts for simulated participants as a random factor. ...
