geom_timeline_label: geom_timeline_label

In tcoopermont/eqtools: Earthquake Tools

Description

This function generates annotation to accompany 'geom_timeline' plot objects. The name of the earthquake location is shown above the timeline point and a line connection the name with the point is drawn.

Usage

geom_timeline_label(mapping = NULL, data = NULL, stat = "identity",
  position = "identity", show.legend = NA, na.rm = FALSE,
  inherit.aes = TRUE, ...)

Arguments

mapping	Set of aesthetic mappings created by <e2><80><98>aes<e2><80><99>. Can be inherited from upper levels of the plot.
data	The data to be displayed in this layer. Can be NULL, data.frame or function
stat	The statistical transformation to use on the data for this layer
position	Position adjustment, either as a string, or the result of a call to a position adjustment function.
show.legend	logical. Should this layer be included in the legends?
na.rm	If <e2><80><98>FALSE<e2><80><99>, the default, missing values are removed with a warning. If <e2><80><98>TRUE<e2><80><99>, missing values are silently removed.
inherit.aes	If <e2><80><98>FALSE<e2><80><99>, overrides the default aesthetics, rather than combining with them.
...	other arguments passed on to <e2><80><98>layer<e2><80><99>.

Details

aes parameters act similar to 'geom_label' aes

• x: a Date object

• y: single integer or a factor. (points will be grouped by y) example: COUNTRY

• n_max: integer max number of labels sorted by size

• size: numeric data field to base limiting of number of labels

• label: character text to be diplayed over points

Examples

## Not run: 
ggplot(quakesFiltered,aes(x = DATE, y = COUNTRY,
        xmin = as.Date("2000-1-1","%Y-%m-%d"),
        xmax = as.Date("2015-12-31","%Y-%m-%d"),
        )) +
 geom_timeline(aes(size = EQ_PRIMARY)) +
 geom_timeline_label(aes(size = EQ_PRIMARY)) +

## End(Not run)
