Function names use underscores to separate verbs.

Preferred

display_plot_again()

Discouraged

DisplayPlotAgain()
displayplotagain()
display.plot.again()

Variable names use underscore separated nouns. A very common alternative is to use a period in place of the underscore. However, the period is often used to identify class hierarchies in R and the period has specific meanings in many database systems which presents an issue when importing from and exporting to databases. See Section 9.14 to rename variables automatically. Preferred

num_frames <- 10

Discouraged

num.frames <- 10
numframes  <- 10
numFrames  <- 10
