nsca_plot: Plot both frontiers

In NSCA: Necessary and Sufficient Condition Analysis

Plot both frontiers

Description

Draws the scatter plot with the necessity and sufficiency frontiers and shades the admissible region between them. Several frontier techniques may be drawn at once; unlike the computation, a chart compares nothing numerically, so mixing techniques here is safe and often informative.

Usage

nsca_plot(model, x = NULL, ceilings = NULL, shade = TRUE, annotate = TRUE)

## S3 method for class 'nsca_result'
plot(x, ...)

Arguments

model	An object returned by nsca_analysis().
x	Optional condition names or positions.
ceilings	Frontier techniques to draw. Defaults to all that were estimated.
shade	Shade the admissible region under the first technique.
annotate	Label the two corners that the claim requires to be empty.
...	Passed on to nsca_plot() by the plot() method.

Value

A ggplot for one condition, or a named list of plots.

Examples

set.seed(1)
x <- sort(runif(60))
dat <- data.frame(X = x, Y = pmin(pmax(x + rnorm(60, 0, 0.1), 0), 1))
fit <- nsca_analysis(dat, "X", "Y", ceilings = "ce_fdh")
nsca_plot(fit)
plot(fit)
