Custom formatting

• create a header word using dplyr::rename_with
• format percentages with presenter::format_percent

diamonds %>% 
  select(-clarity) %>% 
  mutate(relative_price = price / max(price), .before = "x") %>% 
  group_by(across(where(is.ordered))) %>% 
  summarize(across(where(is.double), mean), .groups = "drop") %>% 
  format_percent(relative_price) %>% 
  rename_with(~str_c("category_", .), cut:color) %>% 
  rename_with(~str_c("property_", .), carat:table) %>% 
  rename_with(~str_c("dimension_", .), x:z) -> diamonds_summary

diamonds_summary %>% head

Header words are automatically identified by the following regular expression: "^.*(?=(_|\\.))". Leaving the header_word argument blank produces the same result as providing the commented out argument below. The last id column controls merging and greyscaling. Numeric columns are given some automatic formatting within the make_flextable function.

diamonds_summary %>% 
  make_flextable(last_id_col = 2,
                 # header_words = c("category", "property", "dimension"), 
                 theme = "zebra_gold")

Automatic coloring

tibble(x = letters[1:10],
       y = -5:4,
       z = -c(-.5, -.2, -.1, 0, .1, .2, .3, .4, .6, .9)) %>% 
  format_percent(z) %>% 
  rename_with(~str_c("sample_", .)) %>% 
  make_flextable()

tibble(x = letters[1:10],
       y = -5:4,
       z = -c(-.5, -.2, -.1, 0, .1, .2, .3, .4, .6, .9)) %>% 
  format_percent(z) %>% 
  make_flextable()
