`pdq_functions_exist.Rd`

For a given distribution name, such as "norm", checks to see
whether or not p/d/q functions all exist for that distribution --
such as `pnorm()`

, `dnorm()`

, and `qnorm()`

.
Methods for `eval_cdf()`

, `eval_quantile()`

, and `eval_density/mass()`

suffice as alternatives. Internal function.

`pdq_functions_exist(name)`

- name
Name of the distribution; suffix to p/d/q.

`TRUE`

if p/d/q functions are all available for this distribution;
`FALSE`

otherwise.
