Examples

library(ggplot2)
sample_n_keys(heights,
             size = 10) %>%
  ggplot(aes(x = year,
             y = height_cm,
             group = country)) +
  geom_line()
library(ggplot2)
sample_frac_keys(wages,
                0.1) %>%
  ggplot(aes(x = xp,
             y = unemploy_rate,
             group = id)) +
  geom_line()
