Description

This code uses the web api. It retrieves listing data (latest/new/historic) and does not require an 'API' key.

Usage

crypto_listings(
  which = "latest",
  convert = "USD",
  limit = 5000,
  start_date = NULL,
  end_date = NULL,
  interval = "day",
  quote = FALSE,
  sleep = 0,
  finalWait = FALSE
)

Arguments

which	string Shall the code retrieve the latest listing, the new listings or a historic listing?
convert	string (default: USD) to one or more of available fiat or precious metals prices (fiat_list()). If more than one are selected please separate by comma (e.g. "USD,BTC"), only necessary if 'quote=TRUE'
limit	integer Return the top n records, default is 5000 (max allowed by CMC)
start_date	string Start date to retrieve data from, format 'yyyymmdd'
end_date	string End date to retrieve data from, format 'yyyymmdd', if not provided, today will be assumed
