geom_timeline_label: Make time line labels

In piavat/eqPlotc5: Plot Earthquake Timelines and Maps

Description

This function adds annotations to the timeline plot. There is an option to subset to n_max to select the number of annotated earthquakes ordered by magnitude.

Usage

geom_timeline_label(
  mapping = NULL,
  data = NULL,
  stat = "identity",
  position = "identity",
  ...,
  nudge_x = 0,
  nudge_y = 0,
  na.rm = FALSE,
  show.legend = NA,
  inherit.aes = TRUE,
  n_max
)

Arguments

mapping	List of aesthetic created by aes() to use for plot.
data	The data to be displayed in this layer. NULL, the default, is the data inherited from the plot data as specified in the call to ggplot().
stat	The statistical transformation to use on the data for this layer, as a string.
position	Position adjustment.
...	Other arguments passed on to layer.
nudge_x	Horizontal adjustment to nudge labels by.
nudge_y	Vertical adjustment to nudge labels by.
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? NA, the default, includes if any aesthetics are mapped.
inherit.aes	Will aesthethics be inherited (TRUE/FALSE). If FALSE, overrides the default aesthetics, rather than combining with them.
n_max	Number of labels, ordered by magnitude. Default is 5.

Examples

## Not run: 
readr::read_delim("signif.txt", delim = "\t") %>%
 eq_clean_data() %>%
 dplyr::filter((COUNTRY == "USA" | COUNTRY == "CHINA") & (lubridate::year(DATE) >= 2000 &
                                                            lubridate::year(DATE) <= 2015)) %>%
 ggplot() +
 geom_timeline( aes(x = DATE, y = COUNTRY, size = EQ_PRIMARY, fill = DEATHS)) +

 n_max = 1, size = EQ_PRIMARY)) +
