Plot the results of a calibration check — plot.fp

Plots the coverage (or bias) of one scored quantity against the column of the design that varies, one colour per model. Coverage is shown with an interval of two Monte Carlo standard errors and a dashed line at the nominal level; bias, with a dashed line at zero.

Usage

# S3 method for class 'fp_calibration'
plot(x, parameter = "occ_x", type = c("coverage", "bias"), by = NULL, ...)

Arguments

x: An fp_calibration object from fp_calibrate() or fp_verification_curve().
parameter: Scored quantity to plot, by default the occupancy slope ("occ_x"). See fp_calibrate() for the others.
type: "coverage" (default) or "bias".
by: Name of the design column for the horizontal axis. By default, the first design column that varies among cells; further varying columns become panels. With no varying column, the models are on the axis.
...: Unused.

Value

A 'ggplot2' object, which can be modified with the usual + syntax.

Examples

if (FALSE) { # \dontrun{
cal <- fp_verification_curve(p10 = 0.05, conf_effect = 1.5, conf_cor = 0.7,
                             models = list(constant = ~ 1, fp_on_x = ~ x),
                             reps = 50)
plot(cal)
plot(cal, type = "bias")
} # }
