%description
A collection of utilities that grew out of day-to-day non-life actuarial
work at Com-PASS Advisory. Provides helpers for building chain-ladder
triangles (cumulative, decumulative, run-off, development factors with
optional weighting), constructing exposure columns from policy start/end
dates, parsing Czech birth numbers ('rodné číslo') into dates, generating
smooth RGB color palettes for charts, and loading multi-sheet
'xlsx'/'xlsb' files into a list of data frames. The chain-ladder helpers
follow the standard methodology of Mack (1993)
<doi:10.2143/AST.23.2.2005092>.
