Peek All Intervals Matching a Point

Usage

peek_all_point(
  x,
  point,
  bounds = NULL,
  match_at = c("interval", "start", "end", "either")
)

Arguments

x: An interval_index.
point: Query point.
bounds: Optional boundary override. One of "[)", "[]", "()", "(]". Ignored when match_at is not "interval".
match_at: How the query point is matched against each entry. One of "interval" (default; containment under bounds), "start", "end", or "either". See peek_point() for details.

Value

An interval_index slice of all matches (possibly empty).

Details

The returned interval_index can be inspected with as.list().

Examples

ix <- interval_index("a", "b", "c", start = c(1, 2, 4), end = c(3, 2, 5))
as.list(peek_all_point(ix, 2))
#> [[1]]
#> [1] "a"
#> 

# Entries ending at 3
as.list(peek_all_point(ix, 3, match_at = "end"))
#> [[1]]
#> [1] "a"
#>
