ccwrap                  Wrapper for cross-classified data that
                        standardises rates across a pair of
                        populations. Because these are (r+r')/2 *
                        Q(a_i), this requires 1) doing the rate
                        standardisation on each sub-population, 2)
                        performing the standardisation on the cross
                        classified structure variables, 3) multiplying
                        and (optionally) aggregating up
dg2pop                  Standardisation and decomposition of rates over
                        K rate-factors and 2 populations. We suggest
                        using dgnpop, which will internally call this
                        function.

dg612                   Das Gupta equation 6.12 for a differences
                        between 2 populations when standardised across
                        N populations.
dg_check                Performs some initial checks of the input data
                        for dgnpop(), providing messages where issues
                        are flagged
dg_plot                 Creates a plot of Das Gupta standardised rates
                        across the set of populations
dg_table                Creates a small table of Das Gupta standardised
                        rates. If no populations are specified, rates
                        will be shown for all available populations. If
                        only two populations (or if two particular
                        populations are specified), then
                        rate-differences and 'decomposition effects'
                        are calculated and presented.
