Overview

The goal of coinmarketcapr is to help R developers and Data Scientists to extract and monitor price and market cap of various Cryptocurrencies from 'CoinMarketCap' that lists many leading cryptocurrencies along with their price, 24h trade volume, market cap and much more in USD and other currencies. For more info, check Coinmarketcap API

Installation

The stable version of coinmarketcapr can be installed from CRAN:

install.packages("coinmarketcapr")

And the development version can be installed from Github:

# install.packages("devtools")
devtools::install_github("amrrs/coinmarketcapr")

Dependencies

coinmarketcapr depends on the following packages:

  • jsonlite
  • curl
  • ggplot2

Hence, these packages will be automatically installed while installing coinmarketcapr.

Also note that, coinmarketcapr connects with Coinmarketcap API, hence it requires active internet connection for that.

What's happening

Inside this coinmarketcapr package, The function that you call from coinmarketcapr connects with the Coinmarketcap API using curl (via Internet) and retreives the required data in the form a json file which is then parsed with jsonlite and then flattened/converted to a dataframe and stored in your R Environment in the given variable name.

Getting started

library(coinmarketcapr)
latest_marketcap <- get_global_marketcap('EUR')

coinmarketcapr can be loaded just like any other R-package with library(coinmarketcapr).

Note: coinmarketcapr package requires internet connection to function. If you're trying this behind a Firewall, you might get: Error in open.connection(con, "rb") : Timeout was reached To resolve this error, Please refer this link: Configuring R to Use an HTTP or HTTPS Proxy
