It has nothing to do with round() -- it's the "digits" argument of the print method that controls the number of digits in the output, print.default in this case. And the documentation from print.default says for the digits argument:
"digits: a non-null value for digits specifies the minimum number of significant digits to be printed in values. The default, NULL, uses getOption(digits)...." And, lo and behold, your output shows a minimum of 3 **significant** digits with more being used in tables to line up values that are both greater and less than 1. -- Bert Gunter Genentech Non-Clinical Statistics South San Francisco, CA > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Bob Green > Sent: Thursday, April 19, 2007 2:05 PM > To: [email protected] > Subject: Re: [R] inconsistent output using 'round' > > Peter, > > Many thanks.
