Aesthetics
The following aesthetics can be used with geom_bin2d. Aesthetics are mapped to variables in the data with the aes function: geom_bin2d(aes(x = var)). Note that you do not need quotes around the variable name.
Scales control how the variable is mapped to the aesthetic and are listed after each aesthetic.
| Aesthetic | Default | Related scales |
|---|---|---|
| xmin | required | |
| xmax | required | |
| ymin | required | |
| ymax | required | |
| colour | NA | brewer, gradient, gradient2, gradientn, grey, hue, identity, manual |
| fill | grey60 | brewer, gradient, gradient2, gradientn, grey, hue, identity, manual |
| size | 0.5 | identity, manual, size |
| linetype | 1 | identity, linetype, manual |
| weight | 1 | |
| alpha | 1 |
Layers are divided into groups by the group aesthetic. By default this is set to the interaction of all categorical variables present in the plot.
Parameters
Parameters control the appearance of the geom. In addition to the parameters listed below (if any), any aesthetic can be used as a parameter, in which case it will override any aesthetic mapping.
Returns
This function returns a layer object.
