Dear developeRs,
I have not found anything recent about how to link to a vignette or
other
documentation from within Rd-files. Is this now possible with the new
help
system ? For example, I would like to link to the file AlgDesign.pdf
provided within the doc directory of package AlgDesign.
Yes, you can do it with a \url{} macro. Use a relative link, acting
as though the starting page is located in
/library/AlgDesign/html/*. So \url{../doc/AlgDesign.pdf}
should work from the same package,
\url{../../AlgDesign/doc/AlgDesign.pdf} from elsewhere. Please let
me know if this doesn't work, I haven't tested.

Yes, this works, thanks! Is it also possible to display an
alternative text
instead of the URL itself, like with other links (e.g. show text
"Open pdf"
that operates the link) ?
There's no optional text in the \url{} tag, but you could embed it in
an \ifelse tag, e.g.
\ifelse{html}{\url{ .... }}{ [open pdf ...] }
might work. Using the \ifelse tag will make your package depend on R
>= 2.10.0.
Duncan Murdoch
Another thought: the link only works, if the two packages are installed
in the same library, doesn't it ? Would there be a way to make it work
independently of this restriction ?
Regards, Ulrike
