incase 0.4.0.9000

• Improve formatting of error messages when .exhaustive is TRUE.

incase 0.4.0 (2025-07-24)

• The arguments preserve, default, and ordered have been deprecated in favor of .preserve, .default, and .ordered (#9).
  • Using undotted arguments will now trigger a warning. In future versions, these arguments will be removed.
• Functions in the switch_case(), grep_case(), and fn_case() families gain an .exhaustive argument (#11).
  • When .exhaustive is TRUE, the function will throw an error if any elements of the input are not matched by case statements. This can be useful to ensure you aren't accidentally forgetting to recode any values.
• The position of the .default argument is now taken into account when setting factor levels in *_case_fct() functions (#10).
  • e.g. if the .default argument is given before any case statements, the default value will be the first level of the factor; if the .default argument is positioned in between two case statements, the default value will be ordered in between the value of the two case statements.
• grep_case() and grep_case_fct() now support vectors in the left-hand side of arguments (#8).
• *_case() functions can now use lists as return values (#7).
• *_case() functions no longer perform automatic type conversion on non-atomic return values (#7).

incase 0.3.2 (2023-08-21)

• Accept named arguments with or without preceding dots, e.g. default or .default (#5).
• Take default into account when determining the class of output (#5).
• Fix bug where replacement would fail if a condition evaluated to a vector made up of both NAs and FALSEs with no TRUEs.
• Improve error messages (#5).
• No longer rely on deprecated plu functions (#4).

incase 0.3.1 (2021-06-06)

• Fixed bug where *_case() would return NULL if no conditions were TRUE.
• Added tibble to suggested packages.

incase 0.3.0 (2021-04-03)

New features

• Added *_case_fct() family of functions

  • These work the same as their *_case() equivalents, but return factors
  • Factor levels are determined by the order of case statements.
  • in_case_fct(x < 10 ~ "Low", x < 20 ~ "Medium", default = "High") returns a factor with levels "Low", "Medium", and "High".

• Added *_case_list() family

  • These work the same as their *_case() equivalents, but return lists
  • This allows the functions to return complex data types that would otherwise be broken by automatic type conversion.

• Implemented lazy-ish evaluation of outputs.

  • If the LHS of a formula is never true, the RHS is not evaluated.
    • However, the RHS is still evaluated for all inputs if any input is TRUE.
  • If condition in if_case() never takes one of the three logical values, the corresponding output is not evaluated.

Bug fixes

• if_case() no longer produces an error if condition is only NA.

incase 0.2.1 (2021-01-14)

• Fixed NOTE by removing unnecessary import of stats.
• Uses latest version of plu for more informative error messages.

incase 0.2.0 (2020-12-17)

• Added grep_case() which works similarly to switch_case() but uses pattern matching instead of exact matching.
• Added fn_case() which applies a function to the input and each formula's left-hand side to create the logical vectors used by in_case().
• Added fn_switch_case() which applies a function to the left-hand side of each formula to create the vectors used by switch_case().

incase 0.1.0 (2020-09-15)

• Initial CRAN release.
