Subject: [Rd] str() and signs in imaginary parts (PR#14201)
Message-ID: <20100201194009.F0ED0282EF52@mail.pubhealth.ku.dk>

My unix mailer might not work, so I send the report here:

The function "str" perpetuates the sign of the imaginary part of the 
first array element which it should not:


 > str(c(1+2i,1-3i)); str(c(2-4i,11+3i));
 cplx [1:2] 1+2i 1+3i    # note the faulty 1 + 3i
 cplx [1:2] 2-4i  1-3i    # note the faulty 1 - 3i
 > bug.report()
Have a look at

 >  (xx <- complex(real=rnorm(5,0,1),imag=rnorm(5,0,1)))
[1] -0.686846-0.010655i  1.017494-0.644474i  0.212905-0.720527i
[4] -0.843110+1.538344i -1.341294-0.741398i
 > str(xx,vec.len  = 6)
 cplx [1:5] -0.687-0.011i 1.017-0.644i 0.213-0.721i -0.843-1.538i ...
