Access to current calendaring functions from QuantLib in an easy-to-build smaller package.
As of release 0.1.0, all code is current to the current QuantLib release 1.24 (modulo a small patch set). All of the upstream, i.e. QuantLib, calendars are implemented as are the key access functions.
However, as Quantuccia upstream is stale, we now continue all future work in the qlcal organization on GitHub and its qlcal-r repo with the qlcal R package now also on CRAN. So this repository here will likely not see any future work.
This package started as an integration of the (somewhat experimental) Quantuccia package (see next section) to R by means of Rcpp.
But Quantuccia did not continue beyond its initial proof of concept. As of release 0.0.5, we have now refocused it on an even smaller subset of QuantLib: just the calendaring. So code for pricers, math, models, schedules, … that was in Quantuccia has been removed.
But the calendaring, along with all its support code, is now current with the current QuantLib release which, as of this writing, is 1.24.
Quantuccia is the “little sister” of QuantLib: A header-only subset of which aims to provide the essential parts of QuantLib while being easier to deploy requiring only Boost headers besides itself. (Note that Quantuccia appears to no longer being developed in its upstream repo. However, the idea of only relying on Boost headers is brilliant and carried on here.)
Being header-only makes providing Quantuccia for R a breeze as we can rely on the Rcpp and BH packages. Nothing else is required, and as these packages are available on all relevant platforms, deploying RcppQuantuccia is straightforward.
Here we examine holiday lists for given calendars, specified by country and possibly exchange:
R> library(RcppQuantuccia)
R> fromD <- as.Date("2017-01-01")
R> toD <- as.Date("2017-12-31")
R> getHolidays(fromD, toD) # default calender ie TARGET
[1] "2017-04-14" "2017-04-17" "2017-05-01" "2017-12-25" "2017-12-26"
R> setCalendar("UnitedStates")
R> getHolidays(fromD, toD) # US aka US::Settlement
[1] "2017-01-02" "2017-01-16" "2017-02-20" "2017-05-29" "2017-07-04" "2017-09-04"
[7] "2017-10-09" "2017-11-10" "2017-11-23" "2017-12-25"
R> setCalendar("UnitedStates::NYSE")
R> getHolidays(fromD, toD) # US New York Stock Exchange
[1] "2017-01-02" "2017-01-16" "2017-02-20" "2017-04-14" "2017-05-29" "2017-07-04"
[7] "2017-09-04" "2017-11-23" "2017-12-25"
R>This shows the difference between the default US settlement calendar and the NYSE calendar which we selected explicitly.
As all calendars are now supported (and are listed in a convenience vector calendars):
```r > library(RcppQuantuccia) > calendars [1] “TARGET” “UnitedStates” [3] “UnitedStates/LiborImpact” “UnitedStates/NYSE” [5] “UnitedStates/GovernmentBond” “UnitedStates/NERC” [7] “UnitedStates/FederalReserve” “Argentina” [9] “Australia” “Austria” [11] “Austria/Exchange” “Bespoke” [13] “Botswana” “Brazil” [15] “Brazil/Exchange” “Canada” [17] “Canada/TSX” “Chile” [19] “China” “China/IB” [21] “CzechRepublic” “Denmark” [23] “Finland” “France” [25] “France/Exchange” “Germany” [27] “Germany/FrankfurtStockExchange” “Germany/Xetra” [29] “Germany/Eurex” “Germany/Euwax” [31] “HongKong” “Hungary” [33] “Iceland” “India” [35] “Indonesia” “Israel” [37] “Italy” “Italy/Exchange” [39] “Japan” “Mexico” [41] “NewZealand” “Norway” [43] “Null” “Poland” [45] “Romania” “Russia” [47] “SaudiArabia” “Singapore” [49] “Slovakia” “SouthAfrica” [51] “SouthKorea” “SouthKorea/KRX” [53] “Sweden” “Switzerland” [55] “Taiwan” “Thailand” [57] “Turkey” “Ukraine” [59] “UnitedKingdom” “UnitedKingdom/Exchange” [61] “UnitedKingdom/Metals” “WeekendsOnly” >
We can then for example quickly count number of holiday per calendar (by computing the length of the returned vector of holidays) and show a shortened print, all in a handful of lines continuing from above
> getHols <- function(cal) { # simple helper function
+ setCalendar(cal)
+ getHolidays(as.Date("2022-01-01"), as.Date("2022-12-31"))
+ }
> D <- data.table(calendar=calendars)
> D[ , `:=`(n = length(getHols(calendar)),
+ holidays = paste(format(getHols(calendar),"%d %b"), collapse=",")),
+ by = calendar ]
> D
> D
calendar n holidays

>As of version 0.0.3, we exclude the 7.6 mb header file sobolrsg.hpp, and well as references to it including the model subdirectory using the Sobol-based Brownian Market Models. This shrinks the resulting shared library from around 26 mb (!!) to 0.64 mb, and the (compressed) source tarball from 1.6 mb to 0.24 mb.
As of version 0.0.5, the focus is strictly on calendaring.
As of version 0.1.0, QuantLib files are included ‘as is’ (no longer converted to header-only as Quantuccia did) with a small (documented in a diff) set of changes essentially commenting out headers we no longer need and removed from some of the utilities directories, and turning off pragma instructions we are not allowed to use at CRAN.
The package can be installed from CRAN via
or if you prefer non-release development version these can be installed from GitHub via e.g.
or maybe just checkout the repository locally.
It only requires Rcpp and BH both of which are available whereever R itself runs.
