rv (version 2.3.2)

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 rv
plot(x, y, …)
  # S3 method for rvsummary
plot(x, y, …)

Arguments

x

an rv object

y

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. NOTE. You must call plot.rv explicitly to obtain this behavior. 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'.
