I am calling fft and getting a "non-numeric" error:

+ # Transform range to -pi - pi
+ x <- x - pi
+ x <- x * (2 * pi)/(max(x) - min(x))
+ fft(x)
Error in fft(x) : non-numeric argument
How can I tell what the non-numeric argument is? There is only one argument.
What am I doing wrong?
I guess merge() does something different from what you expect and your x
is a data.frame rather than a vector now....
