## tikzDevice v0.12.3

Yesterday tikzDevice version 0.12.3 made it unto CRAN and is now propagating to the mirrors. The tikzDevice package provides a graphics output device for R that records plots in a LaTeX-friendly format. The device transforms plotting commands issued by R functions into LaTeX code blocks. When included in a paper typeset by LaTeX, these blocks are interpreted with the help of TikZ—a graphics package for TeX and friends written by Till Tantau.

## Using qpdfview with AUCTeX

I recently set up a new computer using Debian Buster with LXQt as desktop environment, which uses qpdfview as default PDF viewer. Obviously I wanted to make use of it when writing LaTeX documents in Emacs using AUCTeX. Mathieu Morey once wrote an explanation how to configure an alternative PDF viewer, which is nowadays archived. However, this explanation uses Emacs’ inbuilt configuration buffers, while I prefer adding simple Emacs Lisp to the initialisation file.
