[R] Looking for knitr example for beginner (NO RStudio)

[Simon Zehnder]

The executable is in case of knitr always Rscript. 
On a mac it is simply Rscript on windows it is Rscript.exe. This should be on your PATH. If you are not sure, open the Mac Terminal and type Rscript --version. If it does not say "Command not found" all is fine. 

Best

If you are trying to compile an Rtex file, this I do not know either (I like the symbols though in for example https://github.com/yihui/knitr-examples/blob/master/005-latex.Rtex). But the .Rnw files are compiled pretty nice in e.g. texmaker, as described in the blog. Use for example this source file: https://github.com/yihui/knitr/blob/master/inst/examples/knitr-minimal.Rnw
