Does R have any built in list of currency symbols (e.g. ¤ £ € $ ¢ ¥ ₧ ƒ) ?

Along the lines of 

letters
 # [1] "a" "b" "c" "d" "e" "f" "g" "h" "i" "j" "k" "l" "m" "n" "o" "p" "q" "r" "s" "t" "u" "v" "w" "x" "y" "z"

but for currencies?

Base R does not have any built in list of currency symbols.

The easiest solution to build one is imho scraping wikipedia list of currencies for data using rvest package.

library(rvest)
library(dplyr)

url <- "https://en.wikipedia.org/wiki/List_of_circulating_currencies"

currency_tab_wiki <- url %>% read_html() %>% 
  html_nodes(xpath = "/html/body/div[3]/div[3]/div[4]/div/table[1]") %>% 
  html_table(fill = TRUE)

currency <- as_tibble(currency_tab_wiki[[1]])

head(currency, 4)

# A tibble: 4 x 6
  `State or territory[1]` `Currency[1][2]`   `Symbol[D] orAbbrev.[3]` `ISO code[2]` Fractionalunit `Numberto basic`
  <chr>                   <chr>              <chr>                    <chr>         <chr>          <chr>
