incase (development version)

  • *_case() functions can now use lists as return values (#7).
  • *_case() functions no longer perform automatic type conversion on non-atomic return values (#7).
  • grep_case() and grep_case_fct() now support vectors in the left-hand side of arguments (#8).

incase 0.3.2

  • 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

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

incase 0.3.0

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

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

incase 0.2.0

  • 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

  • Initial CRAN release.
