Arguments

model

The model to update.

code

A string of the model template or an object inheriting from class mb_code.

gen_inits

A single argument function taking the modified data and returning a named list of initial values.

random_effects

select_data

A named list specifying the columns to select and their associated classes and values as well as transformations and scaling options.

center

A character vector of the columns to center.

scale

A character vector of the columns to scale (after centering).

modify_data

A single argument function to modify the data (in list form) immediately prior to the analysis.

nthin

A count specifying the thinning interval.

new_expr

A string of R code specifying the predictive relationships.

new_expr_vec

A flag specifying whether to vectorize the new_expr code.

modify_new_data

A single argument function to modify new data (in list form) immediately prior to calculating new_expr.
