version 0.2.2

• new functions 'impute' and 'impute_' use pre-fit models to impute datasets.
• new utility function 'foretell'. Replacement for 'predict' that always returns values of the predicted type.
• bugfix: ... arguments were not passed correctly for linear models.

version 0.2.1

• Added support for ridge/elasticnet/lasso regression (using 'glmnet')
• Added support for missForest imputation (using 'missForest')
• Added support for imputation using EM-estimated parameters (using 'norm')
• 'impute_proxy' now supports transformations in the rhs of formula.
• 'impute_median' gains 'type' argument to specify algorithm for median computation.
• New functions 'simputation_capabilities' and 'simputation_suggests' detect which packages supporting imputation methods are available.
• Renamed 'na.action' -> 'na_action' for consistency within simputation.
• Default 'na_action' for 'impute_cart' is now 'na.rpart'
• Default 'na_action' for 'impute_rf' is not 'na.roughfix'
• Complete overhaul of function documentation. Now set up systematically with synopsis of methodology where relevant.
• Dependencies on larger packages (randomForest, glmnet) moved to 'Suggests'
• Fix in 'impute_rf': needed workaround for bug in randomForest 4.6.12 (formulas like Y ~ . - X not handled correctly by predict.randomForest)
• Bugfix in 'impute_pmm': argument 'predictor' was ignored.
• Bugfix in 'impute_rhd': attributes of 'dat' were not always preserved.

version 0.2.0

• Added na.action option for model-based imputation (thanks to Soogeun Park)
• impute_rhd, impute_shd, and impute_knn now have option 'backend="VIM"'
• removed call to structure(NULL,*) to comply to changes in R-devel (thanks to Martin Maechler)

version 0.1.0

• initial release
