[Rd] ** operator

[Tobias Verbeke]

Dear list,

I did not find any mentioning of the fact
that the ** operator can be used as a
synonym for the ^ operator.

 > 5 ** 2
[1] 25

Searching of ** in the R Reference Index only leads
to some examples in the mgcv documentation.

Equally ?"**" does not open the arithmetic
operators help page, but produces

 > ?"**"
No documentation for '**' in specified packages and libraries:
you could try 'help.search("**")'

Is there any reason to this or am I overlooking
something ?

Many thanks in advance,
Tobias
