"There is one chunk name that imbues special behaviour: setup. When you’re in a notebook mode, the chunk named setup will be run automatically once, before any other code is run."

"The goal of conflicted is to provide an alternative conflict resolution strategy. R’s default conflict resolution system gives precedence to the most recently loaded package. This can make it hard to detect conflicts, particularly when introduced by an update to an existing package. conflicted takes a different approach, making every conflict an error and forcing you to choose which function to use."

"fs functions smooth over some of the idiosyncrasies of file handling with base R functions:

• Vectorization. All fs functions are vectorized, accepting multiple paths as input. Base functions are inconsistently vectorized."

"Using facet_wrap() in ggplot2 is a great way to create multiple panelled plots. Though when I am running these, particularly on datasets with different scales, the axis are not as clean as I like."

"I find plotmath expressions to be quite opaque, while LaTeX is a de-facto standard for mathematical expressions, so [latex2exp] package might be useful to others as well."

"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."

"If I have a chunk that reads a data file then modifying the data file doesn't invalidate the cached chunk."

"There seems to be a difference between levels and labels of a factor in R. Up to now, I always thought that levels were the 'real' name of factor levels, and labels were the names used for output (such as tables and plots)."

"Do you ever face a blank script, and not know where to start? This is one reason I find it useful to have a template to follow for my R scripts."
