Instead of a for loop, why not use the vectorization inherent in R?

sigmasqaured <- 1
i <- complex(real = 0, imaginary =1)
f <- seq(0,0.5,0.1)
spectrum
<- (sigmasqaured)/(abs(1-2.7607*exp(2*pi*i*f)+3.8106*exp(4*pi*i*f)-2.6535*exp(6*pi*i*f)+0.9258*exp(8*pi*i*f))^2)

> spectrum
[1] 9.632720e+00 1.411130e+03 2.947753e+00 6.479994e-02 1.295175e-02
