Description Objects from the Class Slots Extends Methods Author(s) See Also Examples

The Dirac distribution with location *l*, by default *=0*, has density
*d(x) = 1* for *x = l*, *0* else.

Objects can be created by calls of the form `Dirac(location)`

.
This object is a `Dirac`

distribution.

`img`

Object of class

`"Naturals"`

: The space of the image of this distribution has got dimension 1 and the name "Real Space".`param`

Object of class

`"DiracParameter"`

: the parameter of this distribution (location), declared at its instantiation`r`

Object of class

`"function"`

: generates random numbers`d`

Object of class

`"function"`

: density function`p`

Object of class

`"function"`

: cumulative function`q`

Object of class

`"function"`

: inverse of the cumulative function`support`

Object of class

`"numeric"`

: a (sorted) vector containing the support of the discrete density function`.withArith`

logical: used internally to issue warnings as to interpretation of arithmetics

`.withSim`

logical: used internally to issue warnings as to accuracy

`.logExact`

logical: used internally to flag the case where there are explicit formulae for the log version of density, cdf, and quantile function

`.lowerExact`

logical: used internally to flag the case where there are explicit formulae for the lower tail version of cdf and quantile function

`Symmetry`

object of class

`"DistributionSymmetry"`

; used internally to avoid unnecessary calculations.
