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)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
rlang::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.
Examples
library(dplyr)
my_lambda <- penalty() %>%
value_set(-4:-1)
try(
range_validate(my_lambda, c(-10, NA)),
silent = TRUE
) %>%
print()
#> [1] "Error in eval(expr, envir, enclos) : Value ranges must be non-missing.\n"
#> attr(,"class")
#> [1] "try-error"
#> attr(,"condition")
#> <error/`Inf` and `unknown()` are acceptable values.>
#> Error:
#> ! Value ranges must be non-missing.
