check_formula_list

Check if an object is NULL, a formula, or a list of formulas and (optionally)
convert it to a list of formulas. If the input is of unknown type or if it
is a list that has entries that are neither <code>formula</code> nor <code>NULL</code>, an error
is thrown.

internal

Joint analysis and imputation of incomplete data in the Bayesian
framework, using (generalized) linear (mixed) models and extensions there of,
survival models, or joint models for longitudinal and survival data, as
described in Erler, Rizopoulos and Lesaffre (2021) <doi:10.18637/jss.v100.i20>.
Incomplete covariates, if present, are automatically imputed.
The package performs some preprocessing of the data and creates a 'JAGS'
model, which will then automatically be passed to 'JAGS'
<https://mcmc-jags.sourceforge.io/> with the help of
the package 'rjags'.
