The Natural History Museum began recording cetacean (whales, dolphins and porpoises) strandings in 1913. I’d like to explore this 1913-1989 dataset.

strandings_df <- read_csv("strandings.csv") %>%
  clean_names() %>% 
  mutate(
    date = date_parse(date, format = "%d/%m/%Y"),
    length = parse_number(length_et),
    species_lumped = fct_lump_n(species, 20),
    across(ends_with("_val"), as.integer)
  )

# glimpse(strandings_df)

Exploratory Some of the species labels contain a question mark or forward slash. This indicates uncertainty, so it might be fun to see if a machine ...
