makeQxDataFrame: Converts one or multiple mortality table objects to a data frame that can be
plotted by plotMortalityTables or plotMortalityTableComparisons
Description
It is not required to call this function manually, plotMortalityTables
will automatically do it if object derived from class mortalityTable
are passed.
Usage
makeQxDataFrame(..., YOB = 1972, Period = NA, reference = NULL)
Arguments
...
Life tables (objects of classes derived from mortalityTable)
YOB
desired year of birth to be plotted as cohort life table (default: 1972)
Period
desired observation year to be plotted (default: NA). If both
YOB and Period are given, a period comparison is generated.
reference
Reference life table, used to show relative death
probabilities (i.e. the q_x for all ages are divided by the
corresponding probabilities of the reference table)
