getdifests: A Function that Creates a Filtered df for DIF plotting

In jsakaluk/psyscores: scripty: Automated Syntax Generation of Measurement Models

Description

This function takes output from difests and filters it to a set of loadings or intercepts. User can specify a vector of items that show significant DIF for intercepts (uniform) or loadings (non-uniform) for later enhanced plotting

Usage

getdifests(out, type = NULL, sig.uni = NULL, sig.nonuni = NULL)

Arguments

out	output df of measurement model parameters from difests
type	whether user wants to extract loading ("loads") or interpts "ints"
sig.uni	an optional character vector of item #s that show significant uniform DIF
sig.nonuni	an optional character vector of item #s that show significant non-uniform DIF

Value

a filtered data frame ready for ggplot

Examples

ests <- getdifests(out, type = "loads", sig.nonuni = sig.nonuni)
