Dirk Eddelbuettel: qlcal 0.1.1 on CRAN: Calendar Updates

By zombie Loading...

The nineteenth release of the qlcal package
arrivied at CRAN just now, and
has already been built for r2u. This version
synchronises with QuantLib 1.42
released this week.

qlcal
delivers the calendaring parts of QuantLib. It is provided (for the R
package) as a set of included files, so the package is self-contained
and does not depend on an external QuantLib library (which can be
demanding to build). qlcal covers
over sixty country / market calendars and can compute holiday lists, its
complement (i.e. business day lists) and much more. Examples
are in the README at the repository, the package page,
and course at the CRAN package
page.

This releases updates to the 2025 holidays for China, Singapore, and
Taiwan.

The full details from NEWS.Rd follow.
