These geom_..._label()
functions able the user to plot labels/text at individual features and/or links.
Users have to indicate how to label the features/links by specifying label = ...
or aes(label = ...
Position of labels can be adjusted with arguments such as vjust
, hjust
, angle
, nudge_y
, etc.
Also check out geom_bin_label()
, geom_seq_label()
or geom_feat_text()
given their resemblance.

Set of aesthetic mappings created by aes()
. If specified and
inherit.aes = TRUE
(the default), it is combined with the default mapping
at the top level of the plot. You must supply mapping
if there is no plot
mapping.
The data to be displayed in this layer. There are three options:
If NULL
, the default, the data is inherited from the plot
data as specified in the call to ggplot()
.
A data.frame
, or other object, will override the plot
data. All objects will be fortified to produce a data frame. See
fortify()
for which variables will be created.
A function
will be called with a single argument,
the plot data. The return value must be a data.frame
, and
will be used as the layer data. A function
can be created
from a formula
(e.g. ~ head(.x, 10)
).
Defines the angle in which the text will be placed. *Note
Moves the text horizontally
Moves the text vertically an entire contig/sequence.
(e.g. nudge_y = 1
places the text to the contig above)
Other arguments passed on to layer()
. These are
often aesthetics, used to set an aesthetic to a fixed value, like
colour = "red"
or size = 3
. They may also be parameters
to the paired geom/stat.
Moves the text vertically
These labeling functions use ggplot2::geom_text()
under the hood.
Any changes to the aesthetics of the text can be performed in a ggplot2 manner.
