Tečkové grafy v ggplot2

ggplot((ilo_data %>% filter(year == 2006))) +
  geom_dotplot(aes(x = working_hours)) +
  labs(x = "Working hours per week",
       y = "Share of countries")

Funkce geom_path()

?geom_path

geom_path() spojuje pozorování v pořadí, v jakém se vyskytují v datech.

ilo_data %>% 
    arrange(country)

# A tibble: 34 x 4
     country   year hourly_compensation working_hours
       <fct>  <fct>               <dbl>         <dbl>

Tečkové grafy v `ggplot2`: funkce `geom_path()`

ggplot() +
    geom_path(aes(x = numeric_variable, y = numeric_variable))

ggplot() +
    geom_path(aes(x = numeric_variable, y = factor_variable))

ggplot() +
    geom_path(aes(x = numeric_variable, y = factor_variable),
                arrow = arrow(___))
