GeomTimeline: GeomTimeline

Description Usage Format Details Value Parameters to Geom Examples

Description

for plotting a time line of earthquakes ranging from xmin to xmaxdates with a point for each earthquake. Optional aesthetics include color, size, and alpha (for transparency).

Usage

1

Format

An object of class GeomTimeline (inherits from Geom, ggproto, gg) of length 5.

Details

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.

Value

foplotting a time line of earthquakes ranging from xmin to xmaxdates with a point for each earthquake

Parameters to Geom

data: A Dataframe Object containing the data to plot.

x: Column of 'data' depicting the x-coordinate of where each of the points will be located.

size: OPTIONAL. Column of 'data' depicting size of each point in the pointsGrob displayed (if missing, the first nmax labels will be displayed).

y: OPTIONAL. Column of 'data' depicting the y-coordinate of where each of the points will be located.

colour: OPTIONAL. Column of 'data' depicting the colour of each point in the pointGrob displayed.

shape: OPTIONAL. Column of 'data' depicting the shape of each of the points.

alpha: OPTIONAL. Column of 'data' which will be used to apply the alpha to each point.

fill: OPTIONAL. Color 'string' (added outside of aes) to modify the default fill of the points (before applying colour).

stroke: OPTIONAL. Stroke of the image (need not be used).
