In jsakaluk/dySEM: Dyadic Structural Equation Modeling

A Function That Writes, Saves, and Exports Syntax for Fitting the I-NULL model for indistinguishable dyads

Description

This function takes the outputted object from scrapeVarCross() and automatically writes, returns, and exports (.txt) lavaan() syntax for the I-NULL model described in Olsen & Kenny (2006)

Usage

scriptINULL(
  dvn,
  lvxname = "X",
  lvyname = NULL,
  writeTo = NULL,
  fileName = NULL
)

Arguments

dvn	input dvn list from scrapeVarCross
lvxname	input character to (arbitrarily) name X LV in lavaan syntax
lvyname	(optional) input character to (arbitrarily) name Y LV in lavaan syntax
writeTo	A character string specifying a directory path to where a .txt file of the resulting lavaan script should be written. If set to “.”, the .txt file will be written to the current working directory. The default is NULL, and examples use a temporary directory created by tempdir().
fileName	A character string specifying a desired base name for the .txt output file. The default is NULL. The specified name will be automatically appended with the .txt file extension. If a file with the same name already exists in the user's chosen directory, it will be overwritten.

Value

character object of lavaan script that can be passed immediately to lavaan functions

qual.inull.script <- scriptINULL(dvn, lvxname = "Qual",
writeTo = tempdir(),
