This is testing for the method returning the eigen value decomposition of a matrix.
The unit test expects 0 (zero) but gets 9.8607613152626476e-32 (fairly small). You can either decide to accept this as close enough to zero and consider the test passed, or investigate more what is your architecture / R install like. Eigen value decomposition is using R's (so BLAS, if I remember correctly); I don't think that this has been reported so far.
