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.
