Those appear to be complex numbers; some place in your script you must be computing something that return a complex number. Do an str on the matrix to see what it says; see if it says this:
> x.1 [,1] [,2] [1,] 0.1820848-0.0000032i 0.1820848-0.0000032i [2,] 0.1820848-0.0000032i 0.1820848-0.0000032i > str(x.1) cplx [1:2, 1:2] 0.182-0i 0.182-0i 0.182-0i ... > If it does, look closely at your script.
