Slight change in api call outcome needed a modification in
crypto_info()
.
After a major change in the api structure of coinmarketcap.com, the package had to be rewritten. As a result, many functions had to be rewritten, because data was not available any more in a similar format or with similar accuracy. Unfortunately, this will potentially break many users implementations. Here is a detailed list of changes:
crypto_list()
has been modified and delivers the same
data as before.exchange_list()
has been modified and delivers the same
data as before.fiat_list()
has been modified and no longer delivers
all available currencies and precious metals (therefore only USD and
Bitcoin are available any more).crypto_listings()
needed to be modified, as multiple
base currencies are not available any more. Also some of the fields
downloaded from CMC might have changed. It still retrieves the latest
listings, the new listings as well as historical listings. The fields
returned have somewhat slightly changed. Also, no sorting is available
any more, so if you want to download the top x CCs by market cap, you
have to download all CCs and then sort them in R.crypto_info()
has been modified, as the data structure
has changed. The fields returned have somewhat slightly changed.crypto_history()
has been modified. It still retrieves
all the OHLC history of all the coins, but is slower due to an increased
number of necessary api calls. The number of available intervals is
strongly limited, but hourly and daily data is still available.
Currently only USD and BTC are available as quote currencies through
this library.crypto_global_quotes()
has been modified. It still
produces a clear picture of the global market, but the data structure
has somewhat slightly changed.Added new options “sort” and “sort_dir” for
crypto_listings()
to allow for the sorting of results,
which in combination with “limit” allows, for example, to only download
the top 100 CCs according to market capitalization that were listed at a
certain date. Correct missing last_historical_data date conversion due
to the now missing field.
Added a new function crypto_global_quotes()
which
retrieves global aggregate market statistics for CMC. There also were
some bugs fixed.
A new function crypto_listings()
is introduced to
retrieve new/latest/historical listings and listing information at CMC.
The option finalWait = TRUE
does not seem to be necessary
any more, also sleep
can be set to ‘0’ seconds.
change limit==1 bug, add interval parameter (offered by pull-request), also change the amount of id splits to allow for max url length 2000
Repaired the history retrieval due to the fact that one api call can only retrieve 1000 data points. Therefore we have to call more often on the api when retrieving the entire history.
Added and corrected a waiter function to wait an additional 60 seconds after the end of the history command before another command could be executed (to not accidentally retrieve the same outdated data). Fixed the waiter.
Due to a change in the web-api of CMC we can only make one call to
the api per minute (else, it will just deliver the same output as for
the first call of the 60 seconds). To reduce the overhang, I have
redesigned the interfaces to retrieve as many ids from one api call as
possible (limited by the 2000 character limitation of the URL). We can
set requestLimit
to increase/decrease the number of
simultaneous ids that are retrieved from CMC.
Rewrite of crypto_info and exchange_info to take similar input as crypto_history. Also extensively updated readme.
Adapt spelling and ’’ for CRAN and explain why I have taken Jesse Vent off the package authors (except function names everything else is new)
Add Exchange functions, delete unnecessary functions, update readme, prepare for submission to cran
NEWS.md
file to track changes to the
package.These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
