plotly_data {plotly} | R Documentation

## Obtain data associated with a plotly graph

### Description

`plotly_data()` returns data associated with a plotly visualization (if there are multiple data frames, by default, it returns the most recent one).

### Usage

    plotly_data(p, id = p$x$cur_data)

    ## S3 method for class 'plotly'
    groups(x)

    ## S3 method for class 'plotly'
    ungroup(x, ...)

    ## S3 method for class 'plotly'
    group_by_(.data, ..., .dots, add = FALSE)

    ## S3 method for class 'plotly'
    summarise_(.data, ..., .dots)

    ## S3 method for class 'plotly'
    mutate_(.data, ..., .dots)

    ## S3 method for class 'plotly'
    do_(.data, ..., .dots)

    ## S3 method for class 'plotly'
    arrange_(.data, ..., .dots)

    ## S3 method for class 'plotly'
    select_(.data, ..., .dots)

    ## S3 method for class 'plotly'
    filter_(.data, ..., .dots)

    ## S3 method for class 'plotly'
    distinct_(.data, ..., .dots)

    ## S3 method for class 'plotly'
    slice_(.data, ..., .dots)

    ## S3 method for class 'plotly'
    rename_(.data, ..., .dots)

    ## S3 method for class 'plotly'
    transmute_(.data, ..., .dots)

### Arguments

`p` | a plotly visualization
`id` | a character string or number referencing an "attribute layer".
`x` | a plotly visualization
`...` | stuff passed onto the relevant method
`.data` | a plotly visualization
`.dots` | Used to work around non-standard evaluation. See vignette("nse") for details
`add` | By default, when add = FALSE, group_by will override existing groups. To instead add to the existing groups, use add = TRUE

### Examples

    # use group_by() to define groups of visual markings
    p <- txhousing %>%
      group_by(city) %>%
      plot_ly(x = ~date, y = ~sales)
    p

    # plotly objects preserve data groupings
    groups(p)
    plotly_data(p)

    # dplyr verbs operate on plotly objects as if they were data frames
    p <- economics %>%
      plot_ly(x = ~date, y = ~unemploy / pop) %>%
      add_lines() %>%
      mutate(rate = unemploy / pop) %>%
      filter(rate == max(rate))
    plotly_data(p)
    add_markers(p)
    layout(p, annotations = list(x = ~date, y = ~rate, text = "peak"))

    # use group_by() + do() + subplot() for trellis displays
    d <- group_by(mpg, drv)
    plots <- do(d, p = plot_ly(., x = ~cty, name = ~drv))
    subplot(plots[["p"]], nrows = 3, shareX = TRUE)

    # arrange displays by their mean
    means <- summarise(d, mn = mean(cty, na.rm = TRUE))
    means %>%
      dplyr::left_join(plots) %>%
      arrange(mn) %>%
      subplot(nrows = NROW(.), shareX = TRUE)

    # more dplyr verbs applied to plotly objects
    p <- mtcars %>%
      plot_ly(x = ~wt, y = ~mpg, name = "scatter trace") %>%
      add_markers()
    p %>% slice(1) %>% plotly_data()
    p %>% slice(1) %>% add_markers(name = "first observation")
    p %>% filter(cyl == 4) %>% plotly_data()
    p %>% filter(cyl == 4) %>% add_markers(name = "four cylinders")
