mditools 0.1.1

Bug fixes

mdi_aggregate() no longer copies its input when it only summarises it (mrg = FALSE), and reads column types in place instead of copying the columns. Its peak memory on a large table drops from about 2.3 to 0.6 times the table’s size.
mdi_hier_apply() orders hierarchy levels by their number, so h_10 comes after h_2 (they were ordered alphabetically).
mdi_clustering() with method = "pam" works again: it stopped with “length(labels) must equal nrow(Xmat)” whenever it was used.
mdi_clustering() with method = "mclust" works without mclust being attached (it stopped with “could not find function mclustBIC”).
mdi_clustering() no longer changes the caller’s random numbers: the seed it sets for reproducible clusters is undone when it returns. Clustering results are unchanged.
mdi_regress() computes confidence intervals with the requested covariance estimator (vcov), matching the standard errors.
mdi_make_conc() is rewritten: codes linked across years form one harmonized group (connected components), which removes the many-to-many join that stopped on large concordances. Each group is named after its smallest code in its latest year, with a D suffix when that year is before the last one. Group membership is unchanged; some group names differ from 0.1.0. year_list now defaults to the concordance’s full year range, and a year without concordance rows is an error.

mdi_import_data() reads tables from an Oracle database (format = "oracle"), through RODBC with the password asked interactively (askpass); both packages are suggested, not required.
mdi_aggregate() and mdi_jointdist() take domVar and domNr for the dominance check, and mdi_jointdist() takes minNumObs.
mdi_outlier() accepts several grouping variables in group.
check_dt(), check_string(), check_choice(), check_char_vec() and hier_levels() are exported, for packages that build on mditools.
