Plot method for the pre_factor function
# S3 method for pre_factor
plot(
x,
plots = c("scree", "change"),
cutoff = 0.2,
shiny = FALSE,
custom = FALSE,
...
)Return value from pre_factor
Plots to return. "change" shows the change in eigenvalues as variables are grouped into different number of factors, "scree" shows a scree plot of eigenvalues
For large datasets plots can take time to render and become hard to interpret. By selection a cutoff point (e.g., eigenvalues of .8 or higher) factors with the least explanatory power are removed from the plot
Did the function call originate inside a shiny app
Logical (TRUE, FALSE) to indicate if ggplot object (or list of ggplot objects) should be returned. This option can be used to customize plots (e.g., add a title, change x and y labels, etc.). See examples and https://ggplot2.tidyverse.org/ for options.
