7.1 Standards

7.1.1 For displaying figures:

7.1.2 For displaying code and even variable names

demo <- function(x) variable_2

7.1.3 For sizing graphs and code-generated plots

  • You can specify out-height or out-width as either pixels, inches, or percentages
  • You can specify both using different units
  • If you specify only one, the other should default to “auto” which keeps the figured scaled as in the original
Code 
plot(pressure)

7.1.4 For code annotation

Code 
library(tidyverse)
1
make a df
2
glimpse a df

7.1.5 For displaying color (like red questions)

this sentence is in red

This is an alternative method but more complex: I love R.

red yellow green blue

yellow background for better contrast

7.1.6 Callouts for questions

8 This is the question you want displayed?
