R: Create interactive raster rectangles

geom_raster_interactive {ggiraph} | R Documentation

## Create interactive raster rectangles

### Description

The geometry is based on `geom_raster()`. See the documentation for those functions for more details.

### Usage

    geom_raster_interactive(...)

### Arguments

`...` | arguments passed to base function, plus any of the `interactive_parameters()`.

### Details for geom_*_interactive functions

The interactive parameters can be supplied with two ways:

- As aesthetics with the mapping argument (via `aes()`). In this way they can be mapped to data columns and apply to a set of geometries.

- As plain arguments into the geom_*_interactive function. In this way they can be set to a scalar value.

### Examples

    # add interactive raster to a ggplot -------
    library(ggplot2)
    library(ggiraph)

    df <- expand.grid(x = 0:5, y = 0:5)
    df$z <- runif(nrow(df))

    gg <- ggplot(df, aes(x, y, fill = z, tooltip = "tooltip")) +
      geom_raster_interactive() +
      scale_fill_gradient_interactive(
        data_id = "coco", onclick = "cici", tooltip = "cucu"
      )

    x <- girafe(ggobj = gg)
    if( interactive() ) print(x)
