[R] inconsistent output using 'round'

[Bob Green]

Peter,

Many thanks. I have never seen a  confidence interval from 0.000 to 
626594160468154480000000000.000 - this is a worry.

I am also still puzzled why use of digits = 3, produced output which 
includes 2, 3 and 4 decimal points as per below. The two decimal 
point values for the coef should have been 2.479, 1.027, 1.614.

regards

Bob
