Description Usage Arguments Note Examples
geom_timeline_label()
is used together with geom_timeline
for adding the annotations to the timeline. The subset is taken
the n_max
number of earthquakes. Aesthetics are x, as the date of
earthquakes and label
would be taken from the column name.

mapping |
Set of aesthetic mappings created by |
data |
The data to be displayed in this layer. There are three options: If A A |
n_max |
A integer which indicates the number of the largest earthquakes to have the label |
stat |
The default set is |
position |
Position adjustment, either as a string, or the result of a call to a position adjustment function. |
na.rm |
If |
show.legend |

inherit.aes |
If |
... |
other arguments passed on to |
The aes xmin
and xmax
as the starting and ending
points of the timeline, which should be clarified.
The aes x
is the date
of the earthquakes
The optiona aes y
is the a factor indicating some stratification
in which case multiple time lines will be plotted for each level of
the factor (e.g. COUNTRY
)
The aes label
is the column in the data frame to obtain
the text annotation
