PLmixed: A package for estimating GLMMs with factor structures.

Description

The PLmixed package's main function is PLmixed, which estimates the model through nested maximizations using the lme4 and optimx packages (previously the optim function). This extends the capabilities of lme4 to allow for estimated factor structures, making it useful for estimating multilevel factor analysis and item response theory models with an arbitrary number of hierarchical levels or crossed random effects.
