Prerequisites

Load the ggplot2 package and set the theme function theme_classic() as the default theme:

library(ggplot2)
theme_set(
  theme_classic() + 
    theme(legend.position = "top")
  )

Basic scatter plots

sp <- ggplot(cars, aes(x = speed, y = dist)) + 
  geom_point()
sp

Change axis ticks break interval

# Break y axis by a specified value
# a tick mark is shown on every 50
sp + scale_y_continuous(breaks=seq(0, 150, by = 50))

# Tick marks can be spaced randomly
sp + scale_y_continuous(breaks=c(0, 50, 65, 75, 150))

Remove breaks

# Remove y tick mark labels and grid lines
sp + scale_y_continuous(breaks=NULL)
