Re: [R] Help need

You need to store the values of each iteration in a vector, and then display the vector after you the loop terminates. I made a few updates to your code, and it seems to do what you want now. And thanks for including the code. That made is easy to know how to help. spectrum = c() for(f in seq

Re: [R] Help need

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 1.4

[R] Help need

I have mad a for loop to try and output values which i have named spectrum. However, I cannot seem to get the answers to come out as a vector which is what i need. They come out as separate values which I am then unable to join together. Thank you for(f in seq(0,0.5,0.1)) { sigmasqaure

I need some help in defining a "print" method for my new S4 class definition. So fer I have worked like this: setClass("MyClass", sealed=F, representation(slot1 = "list",#create a new class slot2= "vector", slot3 = "vector", slot4 = "vector"))
