Overview

RQuantLib connects GNU R with QuantLib.

What is R ?

R is designed as a true computer language with control-flow constructions for iteration and alternation, and it allows users to add additional functionality by defining new functions. For computationally intensive tasks, C, C++ and Fortran code can be linked and called at run time. R is an official part for the GNU Project.

What is QuantLib ?

So what can RQuantLib (currently) do?

Option Pricing

For all of the option types, upon evaluation an element of a simple class is returned. Each of the the specific option classes inherits from a base class Option, and print and summary methods are provided for the base class.

Moreover, another base class ImpliedVolatility is provided with methods print and summary and implied volatility solvers for European and American are provided (Binaries seem to trigger a QuantLib bug as far as I can tell).

For both option and implied volatility calculations, operations are limited to the scalar case. However, using the R, or rather, S object framework makes the work fairly convenient.

Lastly, for the basic European Option, an "array" interface is provided. Here, any of the usual input variables is allow to be in vector form. Solutions are then computed for the "multi-dimensional outer product" of all input vectors. Concretely, if called with three strike prices, four maturities and five volatilities, then 3 * 4 * 5 arrays are returned for the common variables of interest (i.e. value, delta, gamma, ...). In other words, value is now an array over all possible combination of all possible input values. This allows for very compact comparison and scenario analysis.

Fixed Income

The BermudanSwaption function prices a Bermudan swaption with specified strike and maturity (in years), after calibrating the selected short-rate model to an input swaption volatility matrix. Swaption maturities are in years down the rows, and swap tenors are in years along the columns, in the usual fashion. It is assumed that the Bermudan swaption is exercisable on each reset date of the underlying swaps.

Starting with release 0.3.0, a large number of additional Fixed Income functions have become available thanks to the work of Khanh Nguyen that was part of the the Google Summer of Code 2009 program. The new functions include support for (where we list the available help pages):

• CallableBond
• ConvertibleFixedCouponBond
• ConvertibleFloatingCouponBond
• ConvertibleZeroCouponBond
• Enum
• FittedBondCurve
• FixedRateBond
• FixedRateBondCurve
• FixedRateBondPriceByYield
• FixedRateBondYield
• FloatingRateBond
• ZeroCouponBond
• ZeroPriceByYield
• ZeroYield

The Fixed Income functions are a good illustration of the R/C++ interface provided by the Rcpp.

Utilities

What else is there?

Examples

A simple example for EuropeanOption

> library(RQuantLib)
> EO <- EuropeanOption("call", 100, 100, 0.01, 0.03, 0.5, 0.4)
> print(EO)
Concise summary of valuation for EuropeanOption
   value    delta    gamma     vega    theta      rho   divRho
 11.6365   0.5673   0.0138  27.6336 -11.8390  22.5475 -28.3657
> summary(EO)
Detailed summary of valuation for EuropeanOption
   value    delta    gamma     vega    theta      rho   divRho
 11.6365   0.5673   0.0138  27.6336 -11.8390  22.5475 -28.3657
with parameters
         type    underlying        strike dividendYield  riskFreeRate
       "call"         "100"         "100"        "0.01"        "0.03"
     maturity    volatility
        "0.5"         "0.4"

A simple example for EuropeanOptionImpliedVolatility

> EOImpVol <- EuropeanOptionImpliedVolatility("call", value=EO$value+0.50, 100, 100, 0.01, 0.03, 0.5, 0.4)
> print(EOImpVol)
Implied Volatility for EuropeanOptionImpliedVolatility is 0.418
> EOImpVol$impliedVol
[1] 0.4181017

An example of the array-style access

    side = 1, font = 1, oute .... [TRUNCATED]

Download

Alternatively, you can also get RQuantLib from a Comprehensive R Archive Network (CRAN) node in the src/contrib directory.

Lastly, RQuantLib sources are now hosted at R-Forge; please see the RQuantLib page at R-Forge for an overview and access to the SVN archive. Potential contributors are welcome: please register at R-Forge and contact me if you want to contribute.

Installation on Unix

For Debian users, this is as simple as saying apt-get install libquantlib0 libquantlib-dev. Others will have to compile QuantLib, see the QuantLib site.

Generally, for Linux or Unix users, the usual R CMD INSTALL RQuantLib should work from outside R, as should a call to install.packages(). At least, it does on my Debian Linux system.

Feedback and comments are of course welcome in general, and in particular on the installation.

	* R/discount.R: new DiscountCurve function that constructs the
	  spot term structure of interest rates based on

2005-08-06  Dirk Eddelbuettel  

	* Release 0.1.13 matching the new QuantLib 0.3.10 release

	* Implied volatilies are back!
	  With gcc/g++ 4.0, the segmentation fault that I was seeing
	  on implied volatility using gcc/g++ 3.3 (but which others did
	  not see with gcc/g++ 3.2) has disappeared, so the
	  corresponding code has been reactivated.
	* BinaryOptionImpliedVolatility() is also back

	* src/*.cc, R/*.R: Removed a lot of commented-out code

2005-04-26  Dirk Eddelbuettel  

	* Release 0.1.12 matching the upcoming QuantLib 0.3.9 release
	
	* configure.in: Test for QuantLib>= 0.3.8

	* src/*.cc: Several changes for QuantLib 0.3.9:
	  - use Handle<...> instead of RelinkableHandle<...>
	  - use YieldTermStructure instead of TermStructure
	  - use today + length instead of today.plusDays

2004-12-27  Dirk Eddelbuettel  

	* Release 0.1.11 matching the new QuantLib 0.3.8 release

	* configure.in: Added tests for Boost headers, with thanks and
	  a nod to QuantLib for the actual autoconf code

	  'Straddle' now unsupported, hence commented out
	* man/*.Rd: Similarly removed reference to straddle from docs
	
	* src/{barrier_binary.cc,implieds.cc,utils.cc,vanilla.cc}:
	  Renamed BlackScholesStochasticProcess to BlackScholesProcess

2004-09-12  Dirk Eddelbuettel  

	* Release 0.1.10

	* Switched to using Boost library as per QuantLin 0.3.7

	* AmericanOption now uses the Barone-Adesi-Whaley approximation
	
	* Implied volatility for both European and American options
	  currently segfaults when called from R, though the code itself
	  works as standalon. The code also works from R when the implied
	  calculation call is skipped. Something is corrupting memory
	  somewhere. For now, we return NA for either function.

2004-08-06  Dirk Eddelbuettel  

	* DESCRIPTION: Added SystemRequirements for QuantLib

2004-05-26  Dirk Eddelbuettel

	* Release 0.1.8

	* src/{barrier_binary,implieds,utils,vanilla}.cc: Updated to the
	  new QuantLib 0.3.5 pricer framework.	This currently implies
	  that options priced using the binomial engines do not have
	  Greeks; this should be addressed in a future QuantLib release.

	* man/{BarrierOption,AmericanOption}.Rd: Note that Greeks are
	  currently unavailable with binary pricers
	 

2003-11-28  Dirk Eddelbuettel  

	* Release 0.1.7

	* src/barrier_binary.cc:
	  -- split off from RQuantLib.cc
	  -- added three more greeks to Barrier Option
	  -- reflected small change in QuantLib types for Barrier Options

	* src/implieds.cc
	  -- split off from RQuantLib.cc
	  -- rewritten functions for implied volatility on European and
	     American options using new QuantLib framework
	
	* src/utils.cc
	  -- split off from RQuantLib.cc

	* src/vanilla.cc
	  -- rump of RQuantLib.cc, renamed

	  and added explanation to Description
