I guess the confusion here is the relationship between knitr::pandoc() and rmarkdown::render(). The error message you saw was from rmarkdown::render(), which requires Pandoc 1.12.3. The easiest way to go to use rmarkdown (I mean the R package rmarkdown) is to use RStudio, and you don't even need to install Pandoc separately. There are a number of possible reasons for the failure you saw: 1) You didn't install Pandoc; 2) You installed but didn't put it on PATH; 3) You installed a lower version of Pandoc. I don't mean you should not figure out the exact reason, but it just saves so much time not having to take care of such technical details by yourself.
knitr::pandoc() is almost a completely different story. If you are familiar with Pandoc command-line arguments, please feel free to use it. If you don't want to waste time on remembering those arguments, go for rmarkdown::render() instead, which has a much better interface to Pandoc than knitr::pandoc(). As the author of knitr::pandoc(), I can tell you this function was about two afternoon's work, and rmarkdown has been under active development for almost two years now. Hopefully that makes it clear enough for you to choose between knitr::pandoc() and rmarkdown::render() :-) Regards, Yihui -- Yihui Xie <[email protected]> Web: http://yihui.name On Wed, Sep 23, 2015 at 6:13 AM, Ryszard Czermiński <[email protected]> wrote: > I am trying to use R Markdown, but call to render() gives me an error: > Error: pandoc version 1.12.3 or higher is required and was not found. > > As I understand [http://yihui.name/knitr/demo/pandoc/] pandoc is a function > defined in knitr, which I have installed and it has pandoc() function > defined. > > Looks like some version incompatibility issue, but I do not really know how > to resolve it. > Do I need to go to older R version to use it? > > I would appreciate your help. > > Best regards, > Ryszard > >> sessionInfo() > R version 3.2.2 (2015-08-14) > Platform: x86_64-apple-darwin13.4.0 (64-bit) > Running under: OS X 10.10.3 (Yosemite) > other attached packages: knitr_1.11 > [...] > > Ryszard Czerminski > 508-358-6328 > [email protected] > LinkedIn.com/in/Ryszard.Czerminski ______________________________________________ [email protected] mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
