Hi Sonal, The example you gave is not reproducible since we don't have "data" as you do. However, here is an example of how to access the object you are after:
tmp <- CRRBinomialTreeOption(TypeFlag = "pa", S = 50, X = 50, Time = 5/12, r = 0.1, b = 0.1, sigma = 0.4, n = 5) t...@price Cheers, Tal ----------------Contact Details:------------------------------------------------------- Contact me: tal.gal...@gmail.com | 972-52-7275845 Read me: www.talgalili.com (Hebrew) | www.biostatistics.co.il (Hebrew) | www.r-statistics.com (English) ---------------------------------------------------------------------------------------------- On Fri, Dec 24, 2010 at 6:51 AM, sonal <sonal.sar...@arxaa.com> wrote: > > I'm using the CRRBinomialTreeOption function (in package "fOptions") with a > loop for pricing a large number of options.
