Hi there, can anyone tell me how to extract to values of a particular slot for some S4 object? Let take following example:
> library(fOptions) > val <-GBSOption(TypeFlag = "c", S = 60, X = 65, Time = 1/4, r = 0.08, b = > 0.08, sigma = 0.30) > val Title: Black Scholes Option Valuation Call: GBSOption(TypeFlag = "c", S = 60, X = 65, Time = 1/4, r = 0.08, b = 0.08, sigma = 0.3) Parameters: Value: TypeFlag c S 60 X 65 Time 0.25 r 0.08 b 0.08 sigma 0.3 Option Price: 2.133372 Description: Sat Nov 06 19:25:39 2010 Here I have tried with following however slapped with some error: > val@"Option Price" Error: no slot of name "Option Price" for this object of class "fOPTION" What is the ideal way to do that?
