plot.pfGridding: Plot a "pfGridding" object.

Description

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

Usage

# S3 method for pfGridding
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

plot_countries

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