plot.pfGridding: Plot a "pfGridding" object.

Description

Plot maps presenting gridded and transformed charcoal values obtained from the pfGridding function.

Usage

"plot"(x, continuous = TRUE, col_class = NULL, col_lim = NULL, xlim = NULL, ylim = NULL, empty_space = 10, cpal = "YlGn", anomalies = TRUE, file = NULL, points = FALSE, add = NULL, add_color = "white", plot_countries = FALSE, ...)

Arguments

x

An object returned by pfGridding.

continuous

Logical, plot continuous (TRUE) or discrete (FALSE) colors on the map.

col_class

Numeric, if continuous is false define here color classes (single values: col_class=5, or sequences col_class=seq(-15,15,5) are accepted.)

col_lim

Numeric, limits for plotting grid cells values, grid cells with values beyond col_lim are not plotted.

xlim

Numeric, map limits.

ylim

Numeric, map limits.

empty_space

Percentage, define empty space around the map.

cpal

String, color palette to use see brewer.pal

anomalies

Logical, adapt output for plotting anomalies or not (color classes, etc..)

file

Path/Filename.tiff, the function can output a GeoTiff file if desired.

points

Logical, plot charcoal sites on the map?

add

An object of the class "SpatialPolygonsDataFrame" (sp) to be ploted on the map.

add_color

Color of the added SpatialPolygonsDataFrame.

plot_countries

Logical, default FALSE (if TRUE plot countries borderlines and coastlines)

...

Value

A ggplot2 "gg" object that could be further manipulated.
