mapping |
Set of aesthetic mappings created by |
data |
A layer specific dataset - only needed if you want to override the plot defaults. |
geom |
The geometric object to use display the data. |
position |
The position adjustment to use for overlapping points on this layer. |
na.rm |
If |
show.legend |
logical. Should this layer be included in the legends?
