## 1. Exporting & reproducing the data to work further

`dataviewR` provides the additional benefit of allowing you to download or copy the data you are working with, making it easy to export for further analysis, model building, or visualization.

- To download the data, user can use download option provided in .csv or .xlsx formats.
- To copy the data, user is requested to use copy option provided. 

The copy/download feature only applies to the rows currently visible on the page you are viewing. 

`dataviewR` uses the `callr` package to run the shiny application in a background process. To manage and retrieve information about active `dataviewR` sessions, the following helper functions are available.

- `list_dataviewers` → Lists all active `dataviewR` sessions.
- `stop_dataviewer` → To stop a specific or recent `dataviewR` session.
- `stop_all_dataviewers`→ To stop all active `dataviewR` sessions.

## 2. To know the session information

`list_dataviewers` provides information about the active sessions. 

```r
list_dataviewers()
```

```{console}
Active background dataviewer processes:
=======================================

ID: dv_11
  Status: RUNNING
  Data: iris, mtcars
  Port: 5281
  Started: 2025-11-30 18:51:49
```


## 3. To stop `dataviewR` session(s)

To stop a recent dataviewR session user can simply use `stop_dataviewer` function as by default it stops the recent active session.

```r
stop_dataviewer()
```


To stop a specific or recent dataviewR session, user can use `stop_dataviewer` by providing the id of the session. 

```r
id <- dataviewer(mtcars, iris)
dataviewer(id = id)
```
the above code stops the session mentioned in id argument.

To stop all active sessions user needs to use `stop_all_dataviewers` 

```r
stop_all_dataviewers()
```
