Create object NumericGap

Usage

numericGap(
  solution,
  response_identifier = generate_id(type = "gap"),
  points = 1,
  placeholder = "",
  expected_length = size_gap(solution),
  tolerance = 0,
  tolerance_type = "absolute",
  include_lower_bound = TRUE,
  include_upper_bound = TRUE
)

gapNumeric(
  solution,
  response_identifier = generate_id(type = "gap"),
  points = 1,
  placeholder = "",
  expected_length = size_gap(solution),
  tolerance = 0,
  tolerance_type = "absolute",
  include_lower_bound = TRUE,
  include_upper_bound = TRUE
)

Arguments

solution

A numeric value containing the correct answer for this numeric entry.

response_identifier

A character value representing an identifier for the answer. By default, it is generated as 'id_gap_dddd', where dddd represents random digits.

points

A numeric value, optional, representing the number of points for this gap. Default is 1

placeholder

A character value, optional, responsible for placing helpful text in the text input field in the content delivery engine. Default is "".

expected_length

A numeric value, optional, responsible for setting the size of the text input field in the content delivery engine. Default value is adjusted by solution size.

tolerance

A numeric value, optional, specifying the value for the upper and lower boundaries of the tolerance rate for candidate answers. Default is 0.

tolerance_type

A character value, optional, specifying the tolerance mode. Possible values:

  • "exact"

  • "absolute" - Default.

  • "relative"

include_lower_bound

A boolean value, optional, specifying whether the lower bound is included in the tolerance rate. Default is TRUE.

include_upper_bound

A boolean value, optional, specifying whether the upper bound is included in the tolerance rate. Default is TRUE.

Value

An object of class NumericGap
