public_candles() error in timing inputs

[erickwy]

I am trying to collect some historical bitcoin daily data via Coinbase API using 'rgdax' package's "public_candles" command. Thus, I tried the following:

public_candles(product_id = "BTC-USD", start = 2018-01-01, end = 2018-02-01,granularity = 86400)

However, I keep on getting errors as such:

Error in parse_response(path = req.url, query = list(start = start, end = end, : start must be before end

I tried many different permutations of dates but even though the start date is definitely before the end date, I keep getting this same error unfortunately.

May I kindly ask for this help ASAP please?

I am not on a computer right now but on the face of it your date looks to be in the right format. Can you try putting in quotes and let me know. I will look at the code and test it out as soon as I can.

Thanks for confirming. Yes I do also believe my dates are in correct format. What I really do not understand are the errors I am getting as below:

Error in parse_response(path = req.url, query = list(start = start, end = end, : start must be before end

This problem happens whichever dates I input unless I put them as blanks. Many thanks again.

This response message is coming directly from Coinbase . My code does not handle or check for this scenario. I will look into it tomorrow hopefully and get back to you asap.

Thanks. Looking forward to hearing from you.

Based on the latest documentation on coinbase, there is no change in the API params. I was able to replicate the issue and the code works as well with a slight modification. Below is what I tried

public_candles(start = "2018-01-01" , end = "2018-02-01" , granularity = 86400)

The only difference is the date being in quotation. I will update the documentation to reflect the same and may be add an example.

Thank you so much. It works well for me now.

[erickwy]

May I know whether the volume output is in USD or BTC please?

BTC in this case. FYI, this is not package driven. It is defined by the API owned by Coinbase.

Hello. I am trying to do the same historical data collection via Kraken exchange's API. May I know whether there is a codes/packages I can refer to for R platform? Thank you.

[DheerajAgarwal]

Sorry mate. I haven’t built or heard of any.
