[R-sig-finance] question about Asian option pricing arguments

[Muller, John]

Dear Prof. Wuertz,

I am trying to use the fOptions package to check 
the results of my own Asian option pricing code.

In particular I want to check the method
	 TurnbullWakemanAsianApproxOption

I am a bit confused about the input parameters.

What is the difference between the two asset prices
	 S and SA
and between the 2 times
	Time and time

I am guessing S is the initial price and SA is the initial average.

Thank you for your time and thank greatly for these wonderful packages.

best regards,

- john muller
