• Same as previous version.

term 0.4.0.9001

• Internal changes only.

term 0.4.0.9000

• Switching to development version.

term 0.4.0 (2026-08-30)

Breaking changes

• The following functions, deprecated since 0.1.0, are now defunct and error when called (#103).

  • is.term(), replaced by is_term().
  • is.incomplete_terms(), replaced by is_incomplete_terms().
  • is.inconsistent_terms(), replaced by is_inconsistent_terms().
  • parameters() and `parameters<-`(), replaced by pars() and `pars<-`().
  • set_parameters(), replaced by set_pars().
  • tdims(), replaced by tindex().

• The terms argument of pars(), deprecated since 0.2.0, is now defunct (#106). Use pars_terms(as_term(x)) in place of pars(x, terms = TRUE) and pars(x) in place of pars(x, terms = FALSE).

New features

• set_pars() and summary() gain term_rcrd methods (#90).

Bug fixes

• format() now escapes backticks embedded in term names so that printed terms are unambiguous (#90).

Minor improvements

• vctrs (>= 0.4.0) is now the declared minimum, as levels() is implemented for vctrs vectors and the levels.term() and levels.term_rcrd() workarounds are no longer required (#90).

• The purrr dependency is dropped (#103).

• The pars(scalar = NA) compatibility hack for nlist 0.1.0 and 0.1.1 is removed (#90).

• as_list() is imported from extras instead of being copied locally (#90).

• The complete_terms() examples for term_rcrd objects now run (#90).

term 0.3.7 (2026-01-30)

• Fix overly zealous check that now fails on R-devel (#91, #92).
• R (>= 4.1).
• Removed defunct terms argument from npdims().
• Moved following from soft to warn deprecated.
  • as.term()
  • term::pars_terms(scalar =)
  • term::subset(select =)
  • term::term(x =)

term 0.3.6 (2025-01-21)

• Require R (>= 4.0).
• Fixed chk_s3_class() reference in documentation that was causing CRAN NOTE.

term 0.3.5 (2022-09-29)

• Require R (>= 3.5).
• Moved following from soft to warn deprecated
• is.term()
• is.incomplete_terms()
• is.inconsistent_terms()
• parameters()
• parameters<-()
• set_parameters()
• tdims()

term 0.3.4 (2022-03-03)

• Removed deprecated default.stringsAsFactors() from as.data.frame.term_rcrd

term 0.3.3 (2021-09-28)

• Switched order of equality and condition expectations in internal tests.

term 0.3.2 (2021-09-06)

• Internally replaced chk::chkor() with chk::chkor_vld().

term 0.3.1 (2021-02-06)

• Updated internals for lifecycle 1.0.0.

term 0.3.0 (2020-09-25)

Breaking changes

• Stop deprecated terms argument to npdims.term().
• Warn deprecated terms argument to pars.terms().
• nterms() now returns total number of terms not just number of unique non-missing terms.
• is_inconsistent_term() now returns TRUE if includes missing or invalid terms.

Features

Major

• Added term_rcrd class to store vector as underlying data frame and implemented some functions.

Minor

• Added
  • unique().
  • summary().
  • anyDuplicated().
  • scalar_term() to test whether each element in a term vector is scalar.
  • normalize_terms().
  • normalize argument to as_term.character().

Bug Fixes

• Fix as.term() so issues deprecation warning.

term 0.2.0 (2020-06-20)

Breaking changes

• is_complete_terms() now requires same number of duplicate copies.
• chk_term() and vld_term() argument validate now defaults to "complete" and class value is soft-deprecated.
• Soft deprecated
  • as.term() for as_term().
  • is.term() for is_term().
  • is.incomplete_terms() for is_incomplete_terms().
  • is.inconsistent_terms() for is_inconsistent_terms().
  • pars(x, terms = TRUE) for pars_terms(x).
  • subset(select = ) for subset(pars = ).
  • terms argument of npdims().

Features

• Redefined term as a vtcr class with
  • term() constructor which treats unnamed arguments as term values and named values as parameters with their associated dimensions.
  • new_term() to create term vector from character vector without any check.
  • vec_cast() to safely cast character.
• Added pars(scalar = TRUE) and npars(scalar = TRUE).
• Added pars_terms().
• Added scalar_term() to test if each term element is scalar.

Internal

• Use extras from CRAN.
• ndims() and dims() imported from universals and reexported.
• New implementation for repair_terms().

term 0.1.0 (2020-01-15)

• Added chk_term() and vld_term().

term 0.0.1 (2019-12-15)

• Initial release.
