I am trying to find a package in R that will allow me to run multilevel models with a mix of both categorical (independent variables; binary and ordinal data) and continuous data, and use FIML for estimations and deal with missing data. However, based on what i have found so far, I have not been able to find a package that allows me to do all 3 (and not use multiple imputations to deal with missing data).
Would appreciate any suggestions!
