R: Methods for Function q in Package 'distr'

q-methods {distr} | R Documentation

## Methods for Function q in Package ‘distr’

### Description

q-methods

### Methods

q

  `signature(save = "Distribution")`: returns the (left-continuous) quantile function, i.e.; q(s)=inf{t|P(object<=t)>=s}

q.l

  `signature(object = "Distribution")`: from distr-2.6 onwards, we provide this as a synonym for method `q`; this synonym more explicitely states that we are dealing with the left-continuous variant of a quantile function. It is useful in particular when used from the console in RStudio, as RStudio catches calls to `q()` and treats them separately from usual R evaluation. The developers of RStudio have been asked to fix this and comply with standard R evaluation which explicitely allows overloading `q()` as we do it in this package, but so far have refused to do so, as they claim overloading `q()` was insane.

### See Also

`Distribution-class`, `q.r`

### Examples

    require(distr)
    N <- Norm()
    q(N)(0.3)
    ## in RStudio or Jupyter IRKernel, use q.l(.)(.) instead of q(.)(.)
    q.l(N)(0.3)
