Procesamiento

Me interesa la distribución de la cantidad de nutrientes (lípidos, carbohidratos y proteínas) en cinco países (Argentina, Grecia, Italia, Japón y España).

Creo etiquetas para nutrientes y países.

Ocultar código 
nut_tbl <- tibble(
  nut = c("fat", "carbs", "protein"),
  nut_trad = c(
    "Lípidos (g/porción)",
    "Carbohidratos (g/porción)",
    "Proteínas (g/porción)"
  )
)

country_tbl <- tibble(
  country = c("argentinian", "greek", "italian", "japanese", "spanish"),
  pais = c("Argentina", "Grecia", "Italia", "Japón", "España"),
  sym = c("AR", "GR", "IT", "JP", "ES")
)

Filtro por países e incorporo las banderas.

link <- "<img src='https://raw.githubusercontent.com/fonttools/region-flags/refs/heads/gh-pages/png/"

d <- cuisines |>
  mutate(country = tolower(country)) |>
  filter(str_detect(country, "arg|spa|ital|greek|japan")) |>
  select(name, country, calories, fat, carbs, protein, avg_rating) |>
  pivot_longer(
    cols = fat:protein,
    values_to = "valor",
    names_to = "nut"
  ) |>
  drop_na() |>
  full_join(nut_tbl, by = join_by(nut)) |>
  full_join(country_tbl, by = join_by(country)) |>
  mutate(flag = paste0(link, sym, ".png' width=50></img>")) |>
  mutate(flag = fct_reorder(flag, valor))
