missMethods 0.2.0

New functions

impute_in_classes() allows to apply any imputation function inside imputation classes
impute_hot_deck_in_classes() hot deck imputation inside of imputation classes (adjustment cells)
impute_EM() imputes values using EM parameter estimates
imputed_expected_values() imputes expected values from a multivariate normal distribution
impute_LS_adaptive() performs LSimpute_adaptive as described by Bo et al. (2004)
impute_LS_array() performs LSimpute_array as described by Bo et al. (2004)
impute_LS_combined() performs LSimpute_combined as described by Bo et al. (2004)
impute_LS_gene() performs LSimpute_gene as described by Bo et al. (2004)

add cov_only and cor_only as parameter in evaluate_imputation_parameters()
improve vignette “Generating missing values” (add connections to Santos et al. (2019))
rename of cols variables: now all should be named cols_mis, cols_ctrl etc.
rename of ds variables: now all should be named ds_imp, ds_orig etc.
rename of pars variables: now all should be named pars_est or pars_true
sampling of sRHD type cols_seq is no correct, if the donor is only one numeric value
use markdown for documentation of new functions

Functions for the creation of missing values:

delete_MAR_censoring() and delete_MNAR_censoring() create missing (not) at random values using a censoring mechanism
delete_MAR_one_group() and delete_MNAR_one_group() create missing (not) at random values by deleting values in one of two groups
delete_MAR_rank() and delete_MNAR_rank() create missing (not) at random values using a ranking mechanism

Functions for evaluation:

evaluate_imputation_parameters() compares estimated parameters after imputation to true parameters

delete_MAR_1_to_x() and delete_MNAR_1_to_x() can now handle (unordered) factors
new criteria for evaluate_imputed_values() and evaluate_parameters(): six forms of NRMSE, nr_equal, nr_NA and precision
evaluate_imputed_values(): add argument cols_which to select columns for evaluation.

all delete_ functions now take the same first three arguments: ds, p, cols_mis
package now on GitHub and CRAN

Functions for the creation of missing values:

delete_MCAR() creates missing completely at random values in different ways
delete_MAR_1_to_x() and delete_MNAR_1_to_x() create missing (not) at random values using a 1:x mechanism

Functions for imputation:

impute_mean(), impute_median(), impute_mode() different forms of mean, median and mode imputation
impute_sRHD() simple Random Hot-Deck imputation with the possibility to specify a donor limit
apply_imputation() a function to apply aggregating functions for imputation
