is_discrete: Determine whether a distribution is discrete or continuous
Description
Generic functions for determining whether a certain probability distribution
is discrete or continuous, respectively.
Usage
is_discrete(d, ...)
is_continuous(d, ...)
Value
A logical vector indicating whether the distribution(s) in d
is/are discrete or continuous, respectively.
Arguments
d
An object. The package provides methods for distribution
objects such as those from Normal() or Binomial() etc.
...
Arguments passed to methods. Unevaluated arguments will generate a warning to
catch mispellings or other possible errors.
Details
The generic function is_discrete is intended to return TRUE
for every distribution whose entire support is discrete and FALSE
otherwise. Analogously, is_continuous is intended to return TRUE
for every distribution whose entire support is continuous and FALSE
otherwise. For mixed discrete-continuous distributions both methods should
return FALSE.
Methods for both generics are provided for all distribution classes
set up in this package.
