R: getLow, getUp functions of package distr

getLow,getUp {distr} | R Documentation

## getLow, getUp functions of package distr

### Description

getLow, getUp return lower and upper endpoint of a distribution — truncated to lower/upper `TruncQuantile` if infinite; in case of an object of class `"LatticeDistribution"` with infinite lattice length, we search for the smallest/largest point in the lattice which is returned by succesive halving of `x=0.5` in `q(object)(x, lower.tail)` for `lower.tail` `TRUE` resp. `false`.

### Usage

    ## S4 method for signature 'AbscontDistribution'
    getUp(object,
                                          eps = getdistrOption("TruncQuantile"))
    ## S4 method for signature 'DiscreteDistribution'
    getUp(object, ...)
    ## S4 method for signature 'LatticeDistribution'
    getUp(object, ...)
    ## S4 method for signature 'UnivarLebDecDistribution'
    getUp(object,
                                          eps = getdistrOption("TruncQuantile"))
    ## S4 method for signature 'UnivarMixingDistribution'
    getUp(object,
                                          eps = getdistrOption("TruncQuantile"))
    ## S4 method for signature 'AbscontDistribution'
    getLow(object,
                                           eps = getdistrOption("TruncQuantile"))
    ## S4 method for signature 'DiscreteDistribution'
    getLow(object, ...)
    ## S4 method for signature 'LatticeDistribution'
    getLow(object, ...)
    ## S4 method for signature 'UnivarLebDecDistribution'
    getLow(object,
                                          eps = getdistrOption("TruncQuantile"))
    ## S4 method for signature 'UnivarMixingDistribution'
    getLow(object,
                                          eps = getdistrOption("TruncQuantile"))

### Arguments

`object` | a distribution object
`eps` | truncation point (numeric)
`...` | for convenience only; makes it possible to call `getLow`, `getUp` with argument `eps` no matter of the class of `object`; is ignored in these functions.

### Value

`getLow,getUp` | a `numeric` of length 1
