Convert prior data.frame to list

Converts priors defined in a data.frame into a list format for use by stan. In addition it adds "_p" to all variable names in order too allow them to be distinguished from their standard usage within modelling code.

Usage

enw_priors_as_data_list(priors)

Arguments

priors

A data.frame with the following variables: variable, mean, sd describing normal priors. Priors in the appropriate format are returned by enw_reference() as well as by other similar model specification functions.

Value

A named list with each entry specifying a prior as a length two vector (specifying the mean and standard deviation of the prior).
