plot.rv: Plotting Scatterplots of Random Variable Objects

Description

Draw a "random scatter plot" or random points as horizontal or vertical intervals.

Usage

## S3 method for class 'rv':
plot(x, y, \dots)
  ## S3 method for class 'rvsummary':
plot(x, y, \dots)

Arguments

an rv object

random or fixed vector

...

other arguments passed on to plot

Details

If a component x is fixed and the corresponding component of y is random, the resulting `point' is a vertical uncertainty ('credible') interval.

If a component y is fixed and the corresponding component of x is random, the resulting `point' is a horizontal uncertainty ('credible') interval.

If a component of x and the corresponding component of y is random, the resulting `point' is a scatterplot of simulations from the joint distribution of code{(x,y)}.

Compatible with objects of class `rvsummary'.

Examples

Run this code

x <- as.rv(1:30)
  y <- rvnorm(mean=x, sd=1)
  plot(x, y)
  plot(y, x)
  plot(y)
  y <- as.rvsummary(x)
  plot(x, y)
  plot(y, x)
  plot(y)
