Description

R Bindings to the Calendaring Functionality of 'QuantLib'.

'QuantLib' bindings are provided for R using 'Rcpp' via an updated variant of the header-only 'Quantuccia' project (put together initially by Peter Caspers) offering an essential subset of 'QuantLib' (and now maintained separately for the calendaring subset). See the included file 'AUTHORS' for a full list of contributors to both 'QuantLib' and 'Quantuccia'.

RcppQuantuccia: Rcpp bindings for QuantLib Calendering

CI License CRAN Dependencies Downloads Last Commit

Status

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.

Brief History

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.

So what is Quantuccia?

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.

Example

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):

 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 1: TARGET 3 15 Apr,18 Apr,26 Dec 2: UnitedStates 10 17 Jan,21 Feb,30 May,20 Jun,04 Jul,05 Sep,10 Oct,11 Nov,24 Nov,26 Dec 3: UnitedStates/LiborImpact 10 17 Jan,21 Feb,30 May,20 Jun,04 Jul,05 Sep,10 Oct,11 Nov,24 Nov,26 Dec 4: UnitedStates/NYSE 9 17 Jan,21 Feb,15 Apr,30 May,20 Jun,04 Jul,05 Sep,24 Nov,26 Dec 5: UnitedStates/GovernmentBond 11 17 Jan,21 Feb,15 Apr,30 May,20 Jun,04 Jul,05 Sep,10 Oct,11 Nov,24 Nov,26 Dec


58: Ukraine 10 03 Jan,07 Jan,08 Mar,25 Apr,02 May,09 May,13 Jun,28 Jun,24 Aug,14 Oct 59: UnitedKingdom 9 03 Jan,15 Apr,18 Apr,02 May,02 Jun,03 Jun,29 Aug,26 Dec,27 Dec 60: UnitedKingdom/Exchange 9 03 Jan,15 Apr,18 Apr,02 May,02 Jun,03 Jun,29 Aug,26 Dec,27 Dec 61: UnitedKingdom/Metals 9 03 Jan,15 Apr,18 Apr,02 May,02 Jun,03 Jun,29 Aug,26 Dec,27 Dec 62: WeekendsOnly 0


Here we set the year to 2022 as it includes the added US holiday of Juneteenth.

We can also access the calendar 'name' from the underlying (QuantLib Calendar) object:

D[, name := { setCalendar(calendar); getName() }, by=calendar][, .(calendar,name)] calendar name 1: TARGET TARGET 2: UnitedStates US settlement 3: UnitedStates/LiborImpact US with Libor impact 4: UnitedStates/NYSE New York stock exchange 5: UnitedStates/GovernmentBond US government bond market


58: Ukraine Ukrainian stock exchange 59: UnitedKingdom UK settlement 60: UnitedKingdom/Exchange London stock exchange 61: UnitedKingdom/Metals London metals exchange 62: WeekendsOnly weekends only



### A Smaller Subset

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](https://github.com/eddelbuettel/rcppquantuccia/blob/master/local/changes_from_quantlib_1.24.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.

### Installation

The package can be installed from [CRAN](https://cran.r-project.org) via

install.packages("RcppQuantuccia")


or if you prefer non-release development version these can be installed from GitHub via e.g.

remotes::install_github("eddelbuettel/rcppquantuccia")


or maybe just checkout the repository locally.

It only requires `Rcpp` and `BH` both of which are available whereever `R` itself runs.
