era_year_parameters

era_year_label

era_year_days

Extracts a specific parameter from a year unit object constructed by
<code>era_year()</code>.

Provides a consistent representation of year-based time scales as a
numeric vector with an associated 'era'. There are built-in era definitions
for many year numbering systems used in contemporary and historic calendars
(e.g. Common Era, Islamic 'Hijri' years); year-based time scales used in
archaeology, astronomy, geology, and other palaeosciences (e.g.
Before Present, SI-prefixed 'annus'); and support for arbitrary user-defined
eras. Years can converted from any one era to another using a generalised
transformation function. Methods are also provided for robust casting and
coercion between years and other numeric types, type-stable arithmetic with
years, and pretty-printing in tables.
