arulesCBA 1.2.3 (2022-05-24)

  • install_LUCS_KDD_CMAR() and install_LUCS_KDD_CPAR(): Added more checks. This fixes timing issues with untar.

arulesCBA 1.2.1 (2021-11-20)

  • mineCARs now uses by default minimum LHS-support (via parameter originalSupport = FALSE).
  • the CBA_ruleset function is now used consistently as the constructor for CBA objects.
  • added transactionCoverage.
  • added uncoveredClassExamples.
  • added uncoveredMajorityClass.
  • added transactions2DF to convert transactions to a data.frame.
  • RCAR is now faster (does not run glmnet again for the chosen lambda) and returns the whole regularization path.
  • prepareTransactions now automatically add a negative class item if needed.
  • moved the experimental algorithms wCBA and bCBA to Work.
  • R/Weka-based classifiers have now a default class.

arulesCBA 1.2.0 (2020-04-19)

  • Version 1.2.0 has a major interface cleanup. This might require some change in existing code.
  • The classifiers now use as the default a min. confidence of .5 and maxlen of 5 (max. rule length).
  • CBA now includes a default rule in the rule base.
  • added prepareTransactions to discretize and convert a data.frame into transactions.
  • added response to convert class items to class labels (factors).
  • added majorityClass.
  • added FOIL.
  • added RIPPER C4.5, and PART (via RWeka).
  • added PRM, CPAR and CMAR (via LUCS-KDD Software Library).
  • added datasets Mushroom and Lymphography.

arulesCBA 1.1.6 (2020-01-05)

  • maintenance release.

arulesCBA 1.1.5 (2019-11-05)

  • added RCAR (by Tyler Giallanza).
  • The interface for CBA() was updated.
  • CBA now complains if no rules are found.
  • CBA has now also M1 pruning.
  • mineCARs now uses ... to construct the parameters for apriori().

arulesCBA 1.1.4 (2018-12-04)

  • discretizeDF.supervised method mdlp now produces a better error message if it fails.
  • cleaned up the predict code to improve speed.
  • mineCARs has now a balanced support option.
  • convenience function classFrequency added.

arulesCBA 1.1.3-1 (2018-04-23)

  • added new function discretizeDF.supervised for supervised discretization.
  • added new convenience function mineCARs to mine class association rules.
  • the formula interface now parsed the right hand side to restrict the used predictors.
