Hello:
What's the preferred way to link to package documentation from a
vignette using markdown?
My current draft includes
"[cumsum](https://stat.ethz.ch/R-manual/R-devel/library/base/html/cumsum.html)"
to link to the help page for cusum{base} and
"[KFAS](https://rweb.crmda.ku.edu/cran/web/packages/KFAS/KFAS.pdf)" to
link to the pdf documentation for the KFAS package. This works, but it
feels like an ugly hack, and I wonder if there might be some more
elegant way of doing this (documented in a fine manual I have yet to find)?
You can include links that work only when R is displaying the help using
relative URLs like
../../base/help/cumsum
or
../../base/html/cumsum.html
(The former is like doing ?cumsum, i.e. it uses the alias; the latter
goes directly to a page by its name.)
The advantage of this kind of link is it doesn't need an Internet
connection, it works with the R help system; the disadvantage is that it
only works when the help system is running, so those links won't work in
the copy of your vignette on CRAN, for example.
Thanks. I think I saw links like these reading html trying to
find what I needed for [KFAS]; this helps me understand what I read. I
think I'd prefer having links that work in a pdf that I could pass to
someone who may not have R installed.
What's the easiest way to find links like the absolute web
address I gave for [KFAS]? It took me a couple of hours, because I
couldn't find how to get more than "https://rweb.crmda.ku.edu/cran/";
from any of my current web browsers (Safari, Chrome, and SeaMonkey on OS
X 10.11, Internet Explorer, Chrome, FireFox and SeaMonkey under Windows 7).
Thanks again,
Spencer
