Setters, getters, and validators for parameter ranges.
Usage
range_validate(object, range, ukn_ok = TRUE, ..., call = caller_env())
range_get(object, original = TRUE)
range_set(object, range, call = caller_env())Arguments
- object
An object with class
quant_param.- range
A two-element numeric vector or list (including
Inf). Values can includeunknown()whenukn_ok = TRUE.- ukn_ok
A single logical for whether
unknown()is an acceptable value.- ...
These dots are for future extensions and must be empty.
- call
The call passed on to
cli::cli_abort().- original
A single logical. Should the range values be in the natural units (
TRUE) or in the transformed space (FALSE, if applicable)?
Value
range_validate() returns the new range if it passes the validation
process (and throws an error otherwise).
range_get() returns the current range of the object.
range_set() returns an updated version of the parameter object with
a new range.
