I agree with some of this, but I don't see much interest in fixing it.
For example, getting rid of Perl would be a lot of work. When the Perl
scripts were written, R was not capable of doing what they do. I think
it is capable now, but there's still a huge amount of translation work
to do. Who will do that? Who will test that they did it right? At the
end, will it actually have been worth all the trouble? Installing Perl
is not all that hard.

The first sentence here is basically a repetition of "the process is too
complex". I think the second sentence is incorrect. Could you please
point out what necessary steps are missing?

Exactly this has been in the Installation and Administration manual
since I put it there in February for the 2.1.0 release. It's at the
beginning of the appendix on the Windows toolset, with multiple
references pointing people there. It's followed by detailed
descriptions of each of the steps.
If you think it could be further improved, please submit improvements.

As far as I can tell, those all predate the release of 2.1.0. I think
your complaints are out of date.

Secondly, because I use the package.skeleton() function to build 'example' package in the path of D:\Program Files\R\rw2011\ So I must tell R the path where saved the 'example' package. So I write the code is like that. If your path is different from me, you should modify part of these code.
