[ESS] Fwd: Re: [R] .Rd vs. .R, was: matrix multiplication

[Christian Hoffmann]

Hi list,
  I am new here, and I have the following questions:

(1)> I am interested in commissioning lines, functions, regions for 
execution from .Rd using ^C-^F, ^C-^R, ^C-^J,  as one can do from .R 
files. In that way I would be able to check my \examples in .Rd  
directly. Where can this be switched on?

(2)  I find it cumbersomesome that  I have to use \%*\% in .Rd files vs. 
%*% in  .R files. R CMD check will refuse %*% in .Rd files, because it 
thinks there is a comment. I would like to have  %*% in \examples of an 
.Rd files to be able to execute expressions with matrix  multiplication 
from .Rd files directly, but ESS (version 5.13) would  refuse to execute 
this execution, see (1).   What can be done here?

(3) I found out that M-x R  starts R --no-readline , which I want to 
avoid!  I want to browse the history in a (mini?) buffer to search and 
select before execution, using C-up-arrow is cumbersome. I am lazy !

Thanks for help
