[R] adding hyperlinked text to pdf plot

[Yihui Xie]

Sorry I experimented with tikzDevice using \href{}{} but failed.

You can probably try the old image hotspot technique in HTML. I
remember someone did this before in R, but I cannot find the link to
the work now. The key is your need to use the two functions grconvertX
and grconvertY.

Regards,
Yihui
