plotFun.grid: Plot gridded map.

In anacv/plotFun: Helper functions for plotting data

Plot gridded map.

Description

Plot a gridded map, either a single plot or multiplot. A common colorbar is set for a multiplot.

Usage

plotFun.grid(data, lon, lat, lonLims = c(min(lon), max(lon)),
  latLims = c(min(lat), max(lat)), lattice = NULL, breaks = NULL,
  palette = rainbow(10), window.width = 8, window.height = 6,
  title.main = NULL, title.single = NULL, unit.text = NULL,
  cex.main = 1, cex.single = 1, cex.unit = 1, cex.textcbar = 1,
  width.cbar = 0.1, disp.warnings = FALSE, export = FALSE,
  export.format = NULL, export.path = NULL, lon.points = NA,
  lat.points = NA)

Arguments

data	matrix or list of matrices to be plotted. When it is a list, a multiplot is generated (each element of the list is plotted in a subplot).
lon	vector longitudes in strictly ascending order.
lat	vector latitudes in strictly ascending order.
lonLims	2-elemtent vector with the range of longitudes to be plotted. By default all the data is plotted.
latLims	2-elemtent vector with the range of latitudes to be plotted. By default all the data is plotted.
lattice	in multiple plots, 2-element vector giving the number of rows and columns to display the multiplot.
breaks	vector of values defining the intervals to be used in the colorbar.
palette	character vector with the colors for the plot. They will be interpolated to match the number of intervals defined by breaks.
window.width	sets the width of the device window. Modify this argument to improve the appearance. Default:8.
window.height	sets the height of the device window. Modify this argument to improve the appearance. Default:6.
title.main	character string with the main title.
title.single	(optional): in multiple plots, a character vector with the individual titles for single plots.
unit.text	character string to be placed in the colorbar with the units.
cex.main	numeric value giving the title expansion factor. Default: 1.
cex.single	(optional): in multiple plots, numeric value giving the title expansion factor. Default: 1.
cex.unit	numeric value giving the expansion factor of the units text. Default:1.
cex.textcbar	numeric value giving the expansion factor of the text in the colorbar. Default:1.
width.cbar	numeric value giving the fraction of the plot (from 0 to 1) reserved for the colorbar. Modify this argument for a better appearance. Default=0.1
disp.warnings	logical to set if warnings shoul be displayed.
export	logical. If TRUE, the figure is exported as pdf file. Default: False.
export.format	"png" or "pdf" format.
export.path	path (including file name) to save the plot.
lon.points	vector of longitudes for grid points to be marked in the map.
lat.points	vector of latitudes for grid points to be marked in the map.
