Hi,
Using R 2.0.1 on Mac g5 running Mac OS X 10.3.6.
I would expect that
abs(.7 - .5) = abs(.3 - .5) should be returned TRUE.
Instead
www - abs(.7 - .5) = abs(.3 - .5)

[1] FALSE
Is this a result of floating point or the implementation of abs or
something else?
In a function I need to
It's imprecision of floating point representation of real numbers:
print(abs(.7 - .5) - abs(.3 - .5), digit=20)
[1] -5.551115123125783e-17

Hi,
I am looking for a way to extract an interesting part of the match to
a regular expression. For example the pattern [./](*.) matches a
substring that begins with either . or / followed by anything. I am

sub(.*/, , abc/foo)
[1] foo

Dear list members,
This has been a stimulating discussion, now spread over three lists.
Although I'd like to address issues that have been raised on all three
lists, I expect that more or less everyone reads r-help, so I'm just posting
these comments there.
