Error in gamma(delta + (complex(0, 0, 1) * (x - mu))/alpha) : unimplemented complex function
I am trying to obtain the grafic of a pdf . but this error keeps showing .
Here is the code
MXN.fd = function(x,alpha,beta,mu,delta)
{
A = (2*cos(beta/2))^(2*delta)
B = 2*alpha*pi*gamma(2*delta)
C = (beta*(x-mu))/alpha
D = abs(gamma(delta + (complex(0,0,1)*(x-mu))/alpha)^2)
M = A/B*exp(C)*D
M
plot(x,M,type="l",lwd=2,col="red")
}
alpha = 0.02612297
beta = -0.50801886
mu =
