aMNLFA.DIFplot: aMNLFA plotting function for aMNLFA.prune() results

In vtcole/aMNLFA: Automated Moderated Nonlinear Factor Analysis Using 'Mplus'

Description

This function gives the user a plot corresponding to loading, intercept, or threshold DIF from the aMNLFA.prune() function

Usage

aMNLFA.DIFplot(diflist, diftype, log = FALSE)

Arguments

diflist	The listing of results from aMNLFA.prune(), which contains the DIF tables (as well as impact tables, which aren't used here)
diftype	The type of DIF the user wants plot for. Options include "loading" (for loading DIF), "intercept" (for intercept DIF when threshold DIF is not tested), "threshold.highest" (which uses only the largest test statistic across all categories when threshold DIF is tested), and "threshold.all" (which uses the test statistic for all categories when threshold DIF is tested)
log	Logical. If TRUE, plot the y axis on a log scale. Defaults to FALSE.

Value

No return value; generates a plot using base R.

Examples

 wd <- tempdir()
 first<-paste0(system.file(package='aMNLFA'),"/extdata")
 the.list <- list.files(first,full.names=TRUE)
 file.copy(the.list,wd,overwrite=TRUE)
   
 ob <- aMNLFA::aMNLFA.object(dir = wd, 
 mrdata = xstudy, 
 indicators = paste0("BIN_", 1:12),
 catindicators = paste0("BIN_", 1:12), 
 meanimpact = c("AGE", "GENDER", "STUDY"), 
 varimpact = c("AGE", "GENDER", "STUDY"), 
 measinvar = c("AGE", "GENDER", "STUDY"),
 factors = c("GENDER", "STUDY"),
 ID = "ID",
 thresholds = FALSE)
 
 prune.object <- aMNLFA.prune(ob)
 aMNLFA.DIFplot(prune.object, "loading", log = FALSE)
