You are welcome.

The following is intended for the records in the archive in order to protect readers.

Do you mean ?

Not required to call it "cygwin" - also a bit misleading...

Why in C:\Perl ?

Why in c:\mingwin ?

OK, this (1-6) is all described in the R Administration and Installation manual, hence I do not see why we have to repeat it here.

This is described in Writing R Extension and is not related to the setup of you system in 1-6.

This is described in the R Administration and Installation manual and I do not see why we should put the html compiler to the other tools.

There is no DOS environment in Windows NT based operating systems.

I do not see why anybody would like to contaminate the binary installation of R with some development source packages. I'd rather use a separate directory.

I think reading the two mentioned manuals shoul be sufficient. You have not added relevant information. By adding irrelevant information and omitting some relevant information, I guess we got something that is misleading if the reader does NOT read the manuals as well.

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.
