At least two ways:
Way 1: reinstall all those packages from sources using
R CMD INSTALL --html
Way 2: go to the man directory of a source package and apply
R CMD Rdconv --type="html" *.Rd
to all Rd files.
Ok, thanks. That's starting along a helpful path.
The first way sounds dicey on Windows, since some of the packages require tools
that I
probably have installed (e.g., as part of Cygwin), but have never thought about
how to
hook together.
The second way sounds useful if I want to download the source for all the
packages in
addition to the binary installers that I already have.
Is there any way to do this from the Windows binary .zip files, or from the
installations
generated thereby? After all, R generates the HTML on the fly somehow, so the
information
is present; IWBNI there were a way to use that to generate the static HTML.
(Looking
through the installation dirs doesn't show very many .Rd files.)
Ah, sorry, I must have missed your reply.
WEell, internally, you can do somewthing as R's help system does, but it
is documented to be subject to change ("As they are mainly intended for
internal use, their interfaces are subject to change."), see ?Rd2HTML
For package pkg in directory c:/dir on help topic foo you could ask
Rd2HTML(tools:::fetchRdDB("c:/dir/pkg/help/pkg", "foo")) in order to get
a HTML representation. See ?Rd2HTML for details on how to control stuff.
