geom_textdensity | R Documentation |
Line plots of smoothed kernel density estimates are available
in ggplot2 via geom_density
. This geom
layer simply adds a text label to each curve that follow the contour of
the density line when used as a drop-in replacement for
geom_density
geom_textdensity( mapping = NULL, data = NULL, stat = "density", position = "identity", ..., bw = "nrd0", adjust = 1, kernel = "gaussian", n = 512, lineend = "butt", linejoin = "round", linemitre = 10, na.rm = FALSE, show.legend = NA, inherit.aes = TRUE ) geom_labeldensity( mapping = NULL, data = NULL, stat = "density", position = "identity", na.rm = FALSE, show.legend = NA, inherit.aes = TRUE, ..., lineend = "butt", linejoin = "round", linemitre = 10, bw = "nrd0", adjust = 1, kernel = "gaussian", n = 512, label.padding = unit(0.25, "lines"), label.r = unit(0.15, "lines"), arrow = NULL )
mapping |
Set of aesthetic mappings created by |
data |
The data to be displayed in this layer. There are three options: If A A |
stat |
The statistical transformation to use on the data for this layer, as a string. |
position |
Position adjustment, either as a string, or the result of a call to a position adjustment function. |
... |
Other arguments passed on to
|
bw |
The smoothing bandwidth to be used.
If numeric, the standard deviation of the smoothing kernel.
If character, a rule to choose the bandwidth, as listed in
|
adjust |
A multiplicate bandwidth adjustment. This makes it possible
to adjust the bandwidth while still using the a bandwidth estimator.
For example, |
kernel |
Kernel. See list of available kernels in |
n |
number of equally spaced points at which the density is to be
estimated, should be a power of two, see |
lineend |
Line end style (round, butt, square). |
linejoin |
Line join style (round, mitre, bevel). |
linemitre |
Line mitre limit (number greater than 1). |
na.rm |
If |
show.legend |
logical. Should this layer be included in the legends?
|
inherit.aes |
If |
label.padding |
Amount of padding around label. Defaults to 0.25 lines. |
label.r |
Radius of rounded corners. Defaults to 0.15 lines. |
arrow |
Arrow specification, as created by |
A Layer
ggproto object that can be added to a plot.
geom_textdensity()
understands the following aesthetics (required aesthetics are in bold):
x
label
alpha
angle
colour
family
fontface
group
hjust
linecolour
lineheight
linetype
linewidth
size
spacing
textcolour
vjust
In addition to aforementioned aesthetics, geom_labeldensity()
also understands:
boxcolour
boxlinetype
boxlinewidth
fill
The spacing
aesthetic allows fine control of spacing
of text, which is called 'tracking' in typography.
The default is 0 and units are measured in 1/1000 em.
Numbers greater than zero increase the spacing,
whereas negative numbers decrease the spacing.
Learn more about setting these aesthetics
in vignette("ggplot2-specs")
.
