Unique elements, duplicated, ordering and sorting with tagged NAs

Description

These adaptations of base::unique(), base::duplicated(), base::order() and base::sort() treats tagged NAs as distinct values.

Usage

unique_tagged_na(x, fromLast = FALSE)

duplicated_tagged_na(x, fromLast = FALSE)

order_tagged_na(
  x,
  na.last = TRUE,
  decreasing = FALSE,
  method = c("auto", "shell", "radix"),
  na_decreasing = decreasing,
  untagged_na_last = TRUE
)

sort_tagged_na(
  x,
  decreasing = FALSE,
  na.last = TRUE,
  na_decreasing = decreasing,
  untagged_na_last = TRUE
)

Arguments

x	a vector
fromLast	logical indicating if duplication should be considered from the last
na.last	if TRUE, missing values in the data are put last; if FALSE, they are put first
decreasing	should the sort order be increasing or decreasing?
method	the method to be used, see base::order()
na_decreasing	should the sort order for tagged NAs value be
untagged_na_last	should untagged NAs be sorted after tagged NAs? increasing or decreasing?

Examples

x <- c(1, 2, tagged_na("a"), 1, tagged_na("z"), 2, tagged_na("a"), NA)
x %>% print_tagged_na()

unique(x) %>% print_tagged_na()
unique_tagged_na(x) %>% print_tagged_na()

duplicated(x)
duplicated_tagged_na(x)

order(x)
order_tagged_na(x)

sort(x, na.last = TRUE) %>% print_tagged_na()
sort_tagged_na(x) %>% print_tagged_na()
