Make a RAM (Reticular Action Model) from a SEM (structural equation model)

make_sem_ram converts SEM arrow notation to ram describing SEM parameters

Usage

make_sem_ram(sem, variables, quiet = FALSE, covs = variables)

Arguments

sem

structural equation model structure, passed to either specifyModel or specifyEquations and then parsed to control the set of path coefficients and variance-covariance parameters

variables

A character vector listing the set of variables

quiet

Boolean indicating whether to print messages to terminal

covs

A character vector listing variables for which to estimate a standard deviation

Value

An S3-class "sem_ram" containing:

model

Output from specifyEquations or specifyModel that defines paths and parameters

ram

reticular action module (RAM) describing dependencies
