| ggdensity {ggplot} | R Documentation |
Display a smooth density estimate.
ggdensity(plot = .PLOT, aesthetics=list(), ..., data=NULL)
plot |
the plot object to modify |
aesthetics |
named list of aesthetic mappings, see details for more information |

other options, see details for more information |
data |
data source, if not specified the plot default will be used |
Aesthetic mappings that this grob function understands:
x:x position (required)
weight: observation weights
These can be specified in the plot defaults (see ggplot) or
in the aesthetics argument. If you want to modify the position
of the points or any axis options, you will need to add a position scale to
the plot. These functions start with ps, eg.
pscontinuous or pscategorical
Other options:
adjust: see density
for details
kernel: kernel used for density estimation, see density
for details
ggline
weight: observation weights
