ilo_data %>%

# A tibble: 54 x 4
      country   year hourly_compensation working_hours
        <fct>  <fct>               <dbl>         <dbl>

5      Sweden   1982                9.99      29.27885
# ... with 49 more rows

...equivalente a:

ilo_data %>% 
  filter(country == "Sweden" | country == "Switzerland")

La relación entre ambos indicadores

plot_data <- 
  ilo_data %>% 
    filter(year == 2006)

ggplot(plot_data) +
  geom_histogram(
    aes(x = working_hours))

plot_data <- 
  ilo_data %>% 
    filter(year == 2006)

ggplot(plot_data) +
  geom_histogram(
    aes(x = hourly_compensation))

La relación entre ambos indicadores

Añadir etiquetas al gráfico

Un poco de repetición de funciones de dplyr

ilo_data %>%
  group_by(country) %>% 
  summarize(median_working_hours = median(working_hours))

# A tibble: 17 x 2
     country median_working_hours
       <fct>                <dbl>
1    Austria             31.69904
2    Belgium             32.03846
3 Czech Rep.             39.10000
4    Finland             34.04808
5     France             32.34615
# ... with 12 more rows

¡Vamos a practicar!
