The Rorschach protocol.

Source: R/protocols.r

This protocol is used to calibrate the eyes for variation due to sampling. All plots are typically null data sets, data that is consistent with a null hypothesis. The protocol is described in Buja, Cook, Hofmann, Lawrence, Lee, Swayne, Wickham (2009) Statistical inference for exploratory data analysis and model diagnostics, Phil. Trans. R. Soc. A, 367, 4361-4383.

rorschach(method, true = NULL, n = 20, p = 0)

Arguments

method

true

true data set. If NULL, find_plot_data will attempt to extract it from the current ggplot2 plot.
n

total number of samples to generate (including true data)
p

probability of including true data with null data.
