/api/stats/overview

Desc: Blockchain data overview in history

Demo: curl -X Get https://apilist.tronscan.org/api/stats/overview?days=2

@param days: days of statistic data, default 15
@return: list of avgBlockTime, blockchainSize, newAddressSeen, newBlockSeen, newTransactionSeen, totalAddress, totalBlockCount, totalTransaction;

This functionality is to be added to convert_address().

See here for an example of implementation: https://stackoverflow.com/questions/59970499/tron-address-hex-to-base58

Remove the test that <function> throws errors as expected pattern from tests.

This is optional. Maybe, pkgdown-based online docs is enough.

/api/account/list

Currently R-CMD-check is only set up in Actions for Linux environment. But it also has to include Win and Mac OS environments, as per CRAN requirements.

• remove data in the raw_data slot - seems to be useless
• call_value -> amount (NA if absent)?
• convert all hex addresses to base58check
• perform address validation before calling the API (to spare unnecessary calls when an address is not valid)

Transaction info returned by the Tronscan API contains contractType , and integer-encoded type of transaction. This function will convert these integers into human-readable names. The dictionary to be used by this function for mapping is from here (see "Transaction" bullet point):

https://github.com/tronprotocol/documentation/blob/master/English_Documentation/TRON_Virtual_Machine/TRC10_TRX_TRANSFER_INTRODUCTION_FOR_EXCHANGES.md

Function to get transaction info by account address.
Official documentation: https://developers.tron.network/reference#transaction-information-by-account-address

Add more transaction details, as returned by TronScan API:

/api/transaction-info
Desc: List a transaction detail
Demo: curl -X Get https://apilist.tronscan.org/api/transaction-info?hash=1c25bc75d0bebac2f3aa71c350d67c4eed56ec2501b72302ae6d0110dc40cf96
@param hash: query transaction hash;
@return: a transaction detail info;

Add code coverage badge

Error: Can't combine ..1$internal_txs<character> and..5$internal_txs <list>

Various TronGrid API methods operate with timestamps in Unix format. This function will convert Unix timestamps to R's
standard POSIX time values.

Change ...account_address to simply ...address
This is because there is no need to have separate functions to query accounts and contracts separately - the same functions return everything that's needed.

At the moment, there is a lot of duplication when it comes to validating the values of arguments. This can be avoided it such checks are done by a dedicated function.

Format code before release

This function will avoid duplication of code that performs paginated queries.

E.g. functions get_tx_info_by_account_address() and similar.

Function to get account info by address.
Official documentation: https://developers.tron.network/reference#account-info-by-address

Based on public CoinGecko API, see /coins/{id}/market_chart endpoint

Various TronGrid API methods expect timestamps in Unix format. This function will convert standard R's POSIX time values into Unix format.
