Dear R-help,

After making a typo (reminiscent of FORTRAN 77, I guess) I found the
following:

>  identical(all.equal(2^(-10:10), 2**(-10:10)), TRUE)
[1] TRUE

I have tried to find the documentation about the ** operator but I was
unsuccesful this way:

>  sessionInfo()
Version 2.3.1 (2006-06-01)
powerpc-apple-darwin8.6.0

attached base packages:
[1] "methods"   "stats"     "graphics"  "grDevices" "utils"     "datasets"
[7] "base"
>  help("**")
No documentation for '**' in specified packages and libraries:
you could try 'help.search("**")'
>  help.search("\\*\\*")
No help files found with alias or concept or title matching '\*\*'
using regular expression matching.
>  RSiteSearch("**")
A search query has been submitted to http://search.r-project.org
The results page should open in your browser shortly
# --> Too many hits

Where can I find the documentation about the ** operator?

Thanks for any hint,

Jean Lobry
