Description Usage Arguments Value Parameters to Geom Examples
This layer function displays the dates of Earthquakes (coming from your data
) by
presenting each Earthquake, on a straight line, as a point of varying sizes depending on
their Ritcher scale value (based on the size
variable). The Earthquakes are color
coded by the death toll it caused (colour
). If the y
variable is supplied,
the Earthquakes will be displayed in multiple horizontal lines, each line represnting
the quakes for each Country.

Extra Params. *Note: All of the optional arguments above can be applied as columns of the dataset (inside the function aes), or as individual values (outside of the function aes). |
This function adds the lineGrobs and pointGrob into the current graphics device.
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).
*Note: All of the optional arguments above can be applied as columns of the dataset (inside the function aes), or as individual values (outside of the function aes).
