R help - Jun 2005 - is.all.equal

Hi,

The description of all.equal states "is.all.equal should be used for
programming, typically in if expressions. It is a simple wrapper using
identical as shown in the documentation there.", but is.all.equal is
not explicitly defined there (although there is a hint in the comments
that is.all.equal <- function(x,y) isTRUE(all.equal(x,y))).

Could the documentation be corrected? (or even better, how about
defining is.all.equal by default)

Thanks,

Hadley

Hi

It is corrected in the newer R-version. The help page now says: 

'all.equal(x,y)' is a utility to compare R objects 'x' and
'y'
testing "near equality".  If they are different, comparison is
still made to some extent, and a report of the differences is
returned.    Don't use 'all.equal' directly in 'if'
expressions-either use 'isTRUE(all.equal(....))' or 'identical'
if
appropriate.

My R version is:
> version
platform x86_64-unknown-linux-gnu
arch     x86_64                  
os       linux-gnu               
system   x86_64, linux-gnu       
status                           
major    2                       
minor    1.1                     
year     2005                    
month    06                      
day      20                      
language R                       

Best regards,

Where is this documented (including version of the source)?
My recent versions of ?all.equal do not mentio it (at least, I cannot 
find it).
