%description
Creates dummy columns from columns that have categorical variables
(character or factor types). You can also specify which columns to make
dummies out of, or which columns to ignore. Also creates dummy rows from
character, factor, and Date columns. This package provides a significant
speed increase from creating dummy variables through model.matrix().
