[R] Apply rmarkdown::render() outside the RStudio don't find pandoc

[Yihui Xie]

Please check out the instructions here:
https://github.com/rstudio/rmarkdown/blob/master/PANDOC.md

Creating an alias might work, although I have not really tried. What I
have been doing is to uninstall the old version of Pandoc in my
system, and create symlinks following the instructions above. You said

> I try overcome this by creating an alias

but you did not describe what "this doesn't work" really means
(whenever you report something that does not work, please attach the
error message so we do not have to imagine what could be wrong).
Anyway, at least you have to let your system know where is
pandoc-citeproc (per instructions above again), which may or may not
be the problem given the missing error message.

Regards,
Yihui
