phinterval (development version)

Features

• New phint_cumunion(), phint_cumintersect(), phint_symmetric_setdiff() to complete the family of set-operations.

  • phint_cumunion() and phint_cumintersect() take the cumulative union and intersection of a phinterval respectively.

  • phint_symmetric_setdiff() takes the symmetric set-difference of two phintervals.

• New phint_flatten() returns all spans or gaps within an entire phinterval vector as a vector of intervals.

  • New datetime_flatten() returns spans or gaps within a vector of spans defined by start and end points (see also datetime_squash()).

• New is_span() and is_disjoint() to complement is_hole().

  • is_span() and is_disjoint() test whether each element of a phinterval is contiguous or disjoint respectively.

• phint_sift() now keeps or discards spans with lengths in [min_length, max_length], instead of discarding instantaneous spans only.

  • The previous version of phint_sift() was re-named to phint_discard_instants().

Bug fixes

• phint_setdiff() no longer returns a malformed phinterval when phint2 contains instants (#3).

• phint_invert() no longer returns a malformed phinterval when phint contains instants (#9).

Breaking changes

• phint_unnest() now always returns a dataframe with columns key, start, end, and size, instead of optionally including a size column.

The keep_size argument has been removed from phint_unnest() and the function signature has been revised:

# Old Usage
phint_unnest(phint, hole_to = c("drop", "na"), keep_size = FALSE, key = NULL)

# New Usage
phint_unnest(phint, key = NULL, hole_to = c("na", "drop"))

• phint_squash() and datetime_squash() have been split into two functions (#13).

  • phint_squash() and datetime_squash() now always squash intervals into a length-1 <phinterval>.

  • phint_squash_by() and datetime_squash_by() squash intervals within groups defined by the by argument.

  • The order_by argument of phint_squash_by() and datetime_squash_by() now defaults to TRUE, to match the behavior of dplyr::group_by().

  • The na.rm argument of the squash functions has been renamed to na_rm (#19).

The return type of the *_squash() variants is now always a scalar <phinterval> vector, meaning it is safe to use within dplyr::summarize(). This includes cases where the phint argument of phint_squash() or the start, end arguments of datetime_squash() are empty as the empty_to = "empty" option has been removed from the empty_to argument.

The return type of the *_squash_by() variants is now always a tibble() with columns by and phint. Additionally, the keep_by argument has been removed from these variants.

# Old Usage
phint_squash(
  phint,
  by = NULL,
  na.rm = TRUE,
  empty_to = c("hole", "na", "empty"),
  order_by = FALSE,
  keep_by = FALSE
)

# New Usage
phint_squash(
  phint,
  na_rm = TRUE,
  empty_to = c("hole", "na")
)

phint_squash_by(
  phint,
  by,
  na_rm = TRUE,
  empty_to = c("hole", "na"),
  order_by = TRUE
)

• phint_sift() now has additional arguments min_length, max_length, and action.

  • The previous version of phint_sift() (usage phint_sift(phint)) was re-named to phint_discard_instants().

  • Calling phint_sift(phint) without additional arguments now raises an error.
