Description Usage Arguments Details Value Examples
This geom adds a vertical line to each data point with a text annotation (e.g. the location of the earthquake) attached to each line. There is also an option to subset to n_max number of earthquakes, where we take the n_max largest (by magnitude) earthquakes.

mapping |
Set of aesthetic mappings created. |
data |
The data to be displayed in this layer. |
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. |
na.rm |
If 'FALSE', the default, missing values are removed with a warning. If 'TRUE', missing values are silently removed. |
show.legend |
logical. Should this layer be included in the legends? |
inherit.aes |
If FALSE, overrides the default aesthetics, rather than combining with them. |

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. #' @section Aesthetics:

The data to be used with this geom must be downloaded and readed from NOAA site, https://www.ngdc.noaa.gov/nndc/struts/form?t=101650&s=1&d=1.
The geom geom_timeline_label
used with the ggplot
function and the geom_timeline
geom,
add annotations to the n_max largest (by magnitude) earthquakes.
