plot.sia_parallel function

Plot Method for Parallel Analysis Output

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.

## 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)
