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
