Procesamiento

Me interesan los casos cada 100000 habitantes en Argentina.

Filtro los datos para Argentina y agrego la columna y con las unidades de cantidad de casos.

Ocultar código 
d <- filter(who_tb_data, country == "Argentina") |>
  select(year, e_inc_100k) |>
  mutate(l = as.list(e_inc_100k)) |>
  mutate(y = map(l, ~ 1:.x)) |>
  unnest(y)

Defino símbolos para la calavera () y los pulmones ().
