prop_float: Numeric (floating-point) S7 property

In rtemis.core: Core Utilities for the 'rtemis' Ecosystem

Numeric (floating-point) S7 property

Description

The one factory whose name differs from its JSON Schema type: it emits type "number" (which in JSON Schema includes integers), but is named prop_float because declarers think in the integer/float pairing – "number" next to prop_integer invites the same ambiguity as R's "numeric". Accepts R integer values too (class_numeric), floats being a superset of integers.

Usage

prop_float(
  default = NULL,
  min = NULL,
  max = NULL,
  exclusive_min = NULL,
  exclusive_max = NULL,
  nullable = FALSE,
  vector = FALSE,
  min_items = 1L,
  unique_items = FALSE,
  description = ""
)

Arguments

default	Numeric: Default value (NULL for none, or if nullable).
min, max	Numeric or NULL: Inclusive bounds.
exclusive_min, exclusive_max	Numeric or NULL: Exclusive bounds.
nullable	Logical: If TRUE, NULL is a valid value.
vector	Logical: If TRUE, the value is vector-valued (a JSON array).
min_items	Integer: Fewest elements a vector value may hold.
unique_items	Logical: If TRUE, a vector value's elements must be distinct.
description	Character: Human-readable description.

Value

S7 property.

Examples

# Sampling temperature in [0, 2]
temperature <- prop_float(default = 0.3, min = 0, max = 2)
# Learning rate in (0, 1]
lr <- prop_float(default = 0.1, exclusive_min = 0, max = 1)
