Plot method for the goodness function

Plot method for the goodness function

# S3 method for goodness
plot(x, check = "", fillcol = "blue", shiny = FALSE, custom = FALSE, ...)

Arguments

x	Return value from goodness
check	Show plots for variable var. "observed" for the observed frequencies table, "expected" for the expected frequencies table (i.e., frequencies that would be expected if the null hypothesis holds), "chi_sq" for the contribution to the overall chi-squared statistic for each cell (i.e., (o - e)^2 / e), and "dev_std" for the standardized differences between the observed and expected frequencies (i.e., (o - e) / sqrt(e))
fillcol	Color used for bar plots
shiny	Did the function call originate inside a shiny app
custom	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 http://docs.ggplot2.org for options.
...	further arguments passed to or from other methods
