gpindex 0.6.3

• Bumped minimum version of R to >= 4.1.

• geks() is now faster and uses less memory to makes the GEKS index.

• Time periods with entirely missing data no longer return an index value
  with geks(), fixing #8.

• Added a new vignette to better explain decomposing an index.

• Added martini_index() to compute the family of Martini indexes.

• Added kimber_method() for outlier detection.

• Outlier detection functions are now stricter about their inputs.

• Functions for transmuting weights now get a tol argument to control the
  tolerance in the extended mean.

gpindex 0.6.2

• splice_index() now keeps names.

• Fixed a bug with transmute_weights() where the weights could be negative.

• Price-index functions have better argument checking.

gpindex 0.6.1

• Updated maintainer email.

• Added a parameter to generalize geks() by controlling how indexes are
  averaged over the rolling window.

• Fixed a bug where transmute_weights() and factor_weights() could return
  a result with a different length than w.

• Added a new function splice_index() for splicing indexes calculated over
  a rolling window (this was previously sketched in an example).

• transmute_weights() is now faster.

gpindex 0.6.0

• Bumped minimum version of R to at least 4.0.

• The use of ... in grouped() and balanced() is deprecated, and will be removed in a future version. The same behavior can be had by using an anonymous function.

• Added the walsh_geks() function.

• back_period() and base_period() gain a new argument match_first to control whether products in the first period match to themselves or return NA.

• Updated documentation.

• Added a brief vignette.

Version 0.5.0

• back_price() and base_price() have been removed.

• Functions for transforming weights only keep the attributes of the weights (if any), as documented.

• grouped() no longer mangles names.
