plot.idr: Plot IDR predictions

In isodistrreg: Isotonic Distributional Regression (IDR)

Plot IDR predictions

Description

Plot an IDR predictive CDF.

Usage

## S3 method for class 'idr'
plot(
  x,
  index = 1,
  col.cdf = "black",
  lty.cdf = 1,
  xlab = "Threshold",
  ylab = "CDF",
  main = "IDR predictive CDF",
  ...
)

Arguments

x	object of class idr (output of predict.idrfit).
index	single index of the prediction in x for which a plot is desired.
col.cdf	color of the predictive CDF.
lty.cdf	linetype of the predictive CDF.
xlab	label for x axis.
ylab	label for y axis.
main	main title.
...	further arguments to plot.stepfun or plot.

Value

The plotted CDF values (returned invisible).

Examples

data("rain")
require("graphics")

## Postprocess HRES and CTR forecast using data of 2 years

X <- rain[1:(2 * 365), c("HRES", "CTR"), drop = FALSE]
y <- rain[1:(2 * 365), "obs"]

## Fit IDR and plot the predictive CDF when the HRES forecast is 1 mm and
## CTR is 0 mm

fit <- idr(y = y, X = X)
pred <- predict(fit, data = data.frame(HRES = 1, CTR = 0))
plot(pred)
