Description Usage Arguments Details Value Author(s) Examples
Generic function to find the quantiles of a distribution, given the equivalent probability distribution function.

pdist 
Probability distribution function, for example,

p 
Vector of probabilities to find the quantiles for. 
matargs 
Character vector giving the elements of 
scalarargs 
Character vector naming scalar arguments of the distribution function that cannot be vectorised. This is used for the arguments 
... 
The remaining arguments define parameters of the distribution
This may also contain the standard arguments If the distribution is bounded above or below, then this should contain
arguments 
This function is used by default for custom distributions for which a quantile function is not provided.
It works by finding the root of the equation h(q) = pdist(q)  p = 0.
Starting from the interval (1, 1), the interval width is expanded by
50% until h() is of opposite sign at either end. The root is then
found using uniroot
.
This assumes a suitably smooth, continuous distribution.
Vector of quantiles of the distribution at p
