beniplot: Plots earthquakes of depth over a cross-section perpendicular...

In jbrabazon13/quakr: Visualize Earthquake Datasets (one line, title case)

Description

beniplot creates a plot of a cross-sectional transect in either kilometers or longitude versus depth in kilometers. The reference of the transect is perpendicular to north. Therefore, if the fault is not perfectly oriented north-south, then it will be obliquely transected. Use adj_beniplot funtion to account for the strike of the fault. Outputs can be in longitude or kilometers and toggle between showing relative magnitude of events.

Usage

beniplot(data, units = "lon", magnitude = FALSE)

Arguments

data	a dataframe containing at least latitude and longitude of earthquakes as well as the magnitude and depth of the earthquakes. This function was originally designed to work with .csv data exported from https://earthquake.usgs.gov/earthquakes/search/
units	Two units "lon" and "km" can be chosen. "lon" puts the transect in terms of longitude while "km" converts the longitude to kilometers.
magnitude	if magnitude = TRUE a plot showing a transect in km on the x-axis with the y-axis including the earthquake depths categorized in color and size relating depth and magnitude of events is printed. If magnitude = FALSE, a plot of the transect in km and depth in km is printed showing an increase in depth with a gradation of color.

Value

A plot of earthquakes is printed with an x-axis of the transect in kilometers and the y-axis is depth of earthquake in km. A gradation of color illustrates the increase in depth. If the default magnitude = FALSE is changed to magnitude = TRUE, then magnitude of events are shown in correlation with depth.

Examples

beniplot(data = chile, units = "km", magnitude = TRUE)
beniplot(data = dataframe, units = "lon", magnitude = TRUE)
