Thanks for your reply.
I’ve checked your posts and there are lots of nice functions especially the R like summaries and cross correlations and great visualisations.
Concerning crypto currencies, I see you’re using Yahoo web site to get raw data. I didn’t have time to check but I have the impression that they are not listing all available cryptos.
I think coinmarketcap.com has more exhaustive list and is really simple to use their JSON feed.
Anyhow , thanks again for your reply, and I’m looking forward your future posts ;)
