Breaking changes:

  1. Renamed the functions for downloading HICP data to datasets(), datafilters() and data().

  2. Added the new functions aggregate.tree() and disaggregate(). Moved the functionality of aggregate() to aggregate.tree() to highlight that this function is used for the gradual index aggregation following the COICOP tree. The functions aggregate() and disaggregate() can be used for the calculation of user-defined aggregates.

  3. Renamed the argument freq in convert() to type, which is more in line with rates() and contrib().

  4. The function rates() now requires a date vector. Before, the argument t was optional. This change makes the calculation faster, more robust and better aligned to other package functions.

  5. Removed the list of COICOP bundles in coicop.bundles, which are now added to the global package options via options("hicp.coicop.bundles"). This allows users to adjust the list of COICOP bundles.

  6. The function tree() now returns a list with the full COICOP tree at each level. For backward compatibility, the new argument flag=TRUE can be used to still return a logical vector.

New features and other changes:

  1. The function contrib() now allows to derive contributions to monthly, quarterly and annual change rates. This can now also be done for quarterly and annual indices.

  2. The function convert() now allows the calculation of a 12-month moving average.

  3. The function rebase() now allows for multiple index reference periods in t.ref or setting this dynamically to the first or last period.

  4. The functions child() and parent() now allow checking against the full COICOP code dictionary. Moreover, the closest parents/children or the $k$-th parents/children can be derived.

  5. The function aggregate.tree() relies on parent() and level(), which makes it more robust but slightly slower.

  6. Added settings$na.rm for dealing with NAs when quarterly or yearly averages are computed. For na.rm=TRUE, averages are now also calculated if there are NAs or less than 12 observations.

  7. Added settings$freq to set the frequency of the index series manually. Otherwise, the frequency is auto-detected.

  8. Added settings$chatty for printing package specific warnings and messages. This behavior can also be changed globally by options("hicp.chatty").

  9. Removed settings$unbundle. COICOP codes are now always unbundled internally by the respective functions. If that is not wanted by the user, the bundle codes can be set to NA or an empty list can be defined in options(hicp.coicop.bundles).

  10. Years and months are now extracted using the functions data.table::year() and data.table::month(), which is much faster.

  11. All functions using dates now check internally for duplicates to avoid daily or weekly data.

  12. Added the argument pattern="^prc_hicp" to the function datasets().

  13. Added the codes of the new ECOICOP version 2.

Bug fixes:

  1. Fixed a bug in the functions chain() and unchain() when there was a gap of only one year and the index value was set to 100 in December of this year. A break in the time series is now assumed if the calendar year is missing/NA or if only one index value is present in December (for by=NULL) or in the month specified with by.

  2. Fixed a bug in child() for the derivation of children.
