[R] ErrError in f(x, ...) : object 'g.' not found

Hi , R is a new language for me so sorry in advance if this error is to basic for posting. I have tried the R manual and search online for quite a few, if anyone could help i would be very thankful. Here is my code. kappa = 1.1 theta = 0.1 sigma = 0.4 rho = -0.6 v0 = 0.2 r = 0.05 T = 0.5 s0 = 1 K

[R] Problem with integration on Heston model

Hi , I am writing some code to evaluate a price of an option with heston model. My problem is that i need one variable to be generic . Hestonf = function(phi,kappa,theta,sigma,rho,v0,r,T,s0,type) { if (type == 1) { u = 0.5; b = kappa-rho*sigma; } else { u = 0.5;

Hi, i am writing a function to plot a pdf functions of a Generalized normal laplace distribution. The code is this { y = x-rho*mu cf.fn = function(s){ cplex = complex(1,0,1) temp1 = alpha*beta*exp(-sigma*s^2/2) temp2 = (alpha-
