Title: Connecting to trade APIs in R? Post by: RobertJK on August 12, 2011, 04:21:14 PM Does anyone have advice on connecting to the trade APIs through R? It looks like R doesn't support the URl structure for APIs like TradeHill etc... I'm trying to work with the ReadLines function but to no avail... I simply get output that looks like this:
<Code> > readLines("https://api.tradehill.com/APIv1/USD/Orderbook") Error in file(con, "r") : cannot open the connection In addition: Warning message: In file(con, "r") : unsupported URL scheme </Code> I've deduced that this function needs a file suffix (ie it would have to be something like orderbook.php) to be able to download the data. Does anyone have any workarounds that they've used, and/or does anyone have any tricks for connecting to these APIs using R? Title: Re: Connecting to trade APIs in R?

Title: Re: Connecting to trade APIs in R? Post by: RobertJK on August 13, 2011, 01:16:23 AM I actually have a good amount of experience with a bunch of other languages... I just wanted to use R for its statistical upper-hand on virtually ever other language. So no dice on R advice? I guess R's not too popular with the BTC crowd, then :(

This means that R doesn't have https support. Google suggests looking into the package RCurl. Note that I've never programmed in R before. |
