How to make ggplot look like base R graphics

After being steadfastly against anything in R beyond base, I’ve recently been indoctrinated into the tidyverse way of doing things. In particular, ggplot and extensions has made making complicated plots a lot easier than using base graphics (especially ggpubr’s ggarrange() function for labelling panels, which I used to do with mtext()). However, I’ve never been a huge fan of the ggplot aesthetic, being trained from a young age to eschew “chart junk“, like grid lines and unnecessary backgrounds. It’s fairly easy to do, with a few modifications of ggplot’s theme_bw(). Include this code before your ggplot commands:

BibTeX database from PDFs via DOI

This somewhat-ridiculous BASH one-liner will create a BibTeX database file (.bib) from a bunch of PDFs via the Crossref API for DOIs, providing the PDF has a DOI on the first page.  As DOI was introduced in 2000, this will probably not work on vintage PDFs.

Vented versus non-vented Petri dishes

Vented Petri dishes have a small lip on the top edge of the dish that allows the lid to sit a little up from the bottom, allowing for some air flow.  Non-vented Petri dishes allow the lid to sit more or less flat on the bottom.  I was wondering what the best applications are for triple, single and non-vented Petri dishes, and found this guide from Thomas Scientific:

  • Triple vented: aids gaseous exchange. Ideally suited for short term work
  • Single vented: limits gaseous exchange, minimizes evaporation and dehydration. Ideally suited for long term work
  • Non-vented: most suitable for anaerobic and long term work
