(This article was first published on

**Thinking inside the box**, and kindly contributed to R-bloggers)A minor feature release RQuantLib 0.3.9

is now on CRAN and

in Debian.

RQuantLib

combines (some of) the quantitative analytics of

QuantLib with the

R statistical computing environment and language.

Bryan Lewis had suggested to enable

another pricing engine for American Options in order to get (at least some)

*Greeks*. This is now supported by picking

`engine="CrankNicolson"`

as shown in the default example for the

`AmericanOption`

function:

R> library(RQuantLib) R> example(AmericanOption) AmrcnOR> # simple call with unnamed parameters AmrcnOR> AmericanOption("call", 100, 100, 0.02, 0.03, 0.5, 0.4) Concise summary of valuation for AmericanOption value delta gamma vega theta rho divRho 11.3648 NA NA NA NA NA NA AmrcnOR> # simple call with some explicit parameters AmrcnOR> AmericanOption("put", strike=100, volatility=0.4, 100, 0.02, 0.03, 0.5) Concise summary of valuation for AmericanOption value delta gamma vega theta rho divRho 10.9174 NA NA NA NA NA NA AmrcnOR> # simple call with unnamed parameters, using Crank-Nicolons AmrcnOR> AmericanOption("put", strike=100, volatility=0.4, 100, 0.02, 0.03, 0.5, engine="CrankNicolson") Concise summary of valuation for AmericanOption value delta gamma vega theta rho divRho 10.9173 -0.4358 0.0140 NA NA NA NA R>

CRANberries, there is

also a
