roll-plot.Rd
Plot density, distribution function, quantile function, and random generation for the discrete distribution described by a roll expression. See below for more details.
droll_plot(roll, ...) proll_plot(roll, lower.tail = TRUE, ...) qroll_plot(roll, lower.tail = TRUE, ...) rroll_plot(n, roll, ...)
roll | A roll expression (e.g., |
---|---|
... | Other arguments passed on to plotting functions
( |
lower.tail | Whether to calculate |
n | Number of random deviates to return. |
For droll_plot()
, proll_plot()
, and qroll_plot()
a bar plot.
For rroll_plot()
a histogram.
Given a roll expression (i.e., an arithmetic expression involving dice),
r()
calculates the complete distribution of the outcomes. This is possible
because the distribution is discrete and has a finite number of outcomes.
From this distribution, droll_plot()
plots the density, proll_plot()
plots the distribution function, qroll_plot()
plots the quantile function,
and rroll_plot()
plots random deviates.
For more information, see the generating functions: roll.
