knitr with TeXworks

Question

There is a great piece on Yihui's site about using knitr with TeXShop. Taking some time for some self indulgent curiosity here. Is there a way to use knitr as an engine in TeXworks?

Answer 1

You can add knitr as additional engine into TeXworks similar as already shown on the linked demo page for Texmaker (note: I do not know knitr at all and also I’m not a regular user of TeXworks, so some mistakes are possible):

Edit: Yihui added instructions for TeXworks to the already mentioned page Editors for knitr.

• Open the “Preferences” window (can be found in the “Edit” menu) and go to the “Typesetting” tab.

  _{(For next steps see image below.)}

• Then (step 1 one the image) add a new Processing Tool. In the new window give it a name (step 2) and add the executable file (step 3). Last add the needed arguments (step 4); you can add more than one by repeated pressing the plus sign. I also marked the TeXworks variable $basename, there exists a $fullname as well. Press OK.

  _{Edit: And I made a mistake: The arguments must be splitted into two – first argument -e, second knitr::knit2pdf('$basename.$suffix') (this second changed according to Yihui).}

  

Then you can choose this processing tool in the main window from the menu “Typeset” or from the toolbar popdown:
