Helper function for s_count_occurrences_by_grade()

Description

Helper function for s_count_occurrences_by_grade() to insert grade groupings into list with individual grade frequencies. The order of the final result follows the order of grade_groups. The elements under any-grade group (if any), i.e. the grade group equal to refs will be moved to the end. Grade groups names must be unique.

Usage

h_append_grade_groups(
  grade_groups,
  refs,
  remove_single = TRUE,
  only_grade_groups = FALSE
)

Arguments

grade_groups	(named list of character) list containing groupings of grades.
refs	(named list of numeric) named list where each name corresponds to a reference grade level and each entry represents a count.
remove_single	(flag) TRUE to not include the elements of one-element grade groups in the the output list; in this case only the grade groups names will be included in the output. If only_grade_groups is set to TRUE this argument is ignored.
only_grade_groups	(flag) whether only the specified grade groups should be included, with individual grade rows removed (TRUE), or all grades and grade groups should be displayed (FALSE).

Value

Formatted list of grade groupings.

Examples

h_append_grade_groups(
  list(
    "Any Grade" = as.character(1:5),
    "Grade 1-2" = c("1", "2"),
    "Grade 3-4" = c("3", "4")
  ),
  list("1" = 10, "2" = 20, "3" = 30, "4" = 40, "5" = 50)
)

h_append_grade_groups(
  list(
    "Any Grade" = as.character(5:1),
    "Grade A" = "5",
    "Grade B" = c("4", "3")
  ),
  list("1" = 10, "2" = 20, "3" = 30, "4" = 40, "5" = 50)
)

h_append_grade_groups(
  list(
    "Any Grade" = as.character(1:5),
    "Grade 1-2" = c("1", "2"),
    "Grade 3-4" = c("3", "4")
  ),
  list("1" = 10, "2" = 5, "3" = 0)
)
