# R API Client

R is an open-source programming language, popularly used for statistical computing and data analysis. The CM official R client provides a simple way to access all data available via the Coin Metrics' API using the R programming language. **Please note this is an initial implementation and is considered a beta product.**

Detailed documentation & installation instructions can be found on [GitHub](https://github.com/coinmetrics/api-client-r). Use this client to query all kinds of data. By default, data from the API is returned as a tibble so it can be easily manipulated. For every API endpoint supported in the Coin Metrics [API Reference](https://docs.coinmetrics.io/api/v4), there is a related function that follows the same format.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://gitbook-docs.coinmetrics.io/access-our-data/r-client.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
