bubbleplot

Bubble plot (generic)

Description

The function allows to generate a bubble plot of a given variable. If the parameter range is not provided, the function estimates the coordinate range of the plot using the points' coordinates extension.

Usage

bubbleplot(x, y, data, variable, range = NA,inches=0.1, interval = "equal",
land=countries, d1 = depth_1, d2= depth_2, d3 = depth_3)

Arguments

`x`	the x coordinates (longitude) of points in the plot.
`y`	the y coordinates (latitude) of points in the plot.
`data`	data frame containing thae variable to be plotted
`variable`	character value of the variable name in `data`
`range`	vector of the coordinates limits of the plot in the form of `c(xmin,xmax, ymin,ymax)`.
`inches`	maximum dimension of the circles expressed in inches.
`interval`	character variable indicating the type of breaks to be computed for the five value levels. Allowed values: `"equal"` and `"quantiles"`.
`land`	shapefile of the world's land
`d1`	shapefile of the 50m bathymetrical line
`d2`	shapefile of the 200m bathymetrical line
`d3`	shapefile of the 800m bathymetrical line

Value

The function returns the bubble plot map of a given variable in a selected range of coordinates.
