plot.sia_parallel: Plot Method for Parallel Analysis Output

In patriciamar/ShinyItemAnalysis: Test and Item Analysis via Shiny

Plot Method for Parallel Analysis Output

Description

You can call this method to plot an existing object resulting from fa_paralell() function, which behaves as a standard data.frame, but can be automatically recognized and processed with a dedicated plot method. Also, you can post-hoc disable the Kaiser boundaries shown by default.

Usage

## S3 method for class 'sia_parallel'
plot(x, y, ...)

Arguments

x	object of class sia_parallel to plot.
y	ignored
...	additional argument: show_kaiser logical, whether to show horizonal lines denoting Kaiser boundaries (eigenvalue 0 and/or 1 for FA and/or PCA, respectively). Defaults to TRUE.

Examples

## Not run: 
fa_parallel_result <- BFI2[, 1:60] |> fa_parallel(plot = FALSE) # without plot
fa_parallel_result |> plot() # generate plot from "fitted" object
fa_parallel_result |> plot(show_kaiser = FALSE) # hide Kaiser boundaries

## End(Not run)
