In JJNewkirk/NOAAEQ: Visualize NOAA EQ data

The wrapper is just to plot the object. See ggplot2 package documenation for more specifics on geom_* and layer_* functions.

geom_timeline(mapping = NULL, data = NULL, stat = "identity",
  position = "identity", xmindate = lubridate::make_date(-6000, 1, 1),
  xmaxdate = lubridate::make_date(6000, 1, 1), ..., na.rm = TRUE,
  show.legend = NA, inherit.aes = TRUE)

`mapping`	Set of aesthetic mappings created by `aes` or `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.
`data`	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.
`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.
`xmindate`	This is a date that will filter data prior to plotting. No EQ prior to this parameter will be plotted.
`xmaxdate`	This is a date that will filter data prior to plotting. No EQ after this parameter will be plotted.
`...`	other arguments passed on to `layer`. These are often aesthetics, used to set an aesthetic to a fixed value, like `color = "red"` or `size = 3`. They may also be parameters to the paired geom/stat.
`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. `FALSE` never includes, and `TRUE` always includes.
`inherit.aes`	If `FALSE`, overrides the default aesthetics, rather than combining with them. This is most useful for helper functions that define both data and aesthetics and shouldn't inherit behaviour from the default plot specification, e.g. `borders`.

x This aesthetic should be a date field as this is mean to be a timeline.

y This aesthetic is used to group EQ in some fashion. For example, y could be set to a country which would subsequently plot each COuntries EQ on a separate line.

See geom_timeline_lable to provide text based annotations to the timeline
