colsymbol: Plot colored symbols

In geo: Draw and Annotate Maps, Especially Charts of the North Atlantic

Description

Adds colored symbols in a variety of shapes to a geo-plot.

Usage

colsymbol(lat, lon, z, circles, squares, rectangles, hbars, vbars, 
  perbars, parbars, levels, nlevels, colors, white, n, maxcol, digits, 
  label.location, labels, fill.circles, density, angle, rotate, 
  minsym = "<", label.resolution = 0, col = 1, labels.only = F, 
  open.circles, lwd, border = F, bordercol = 0)

Arguments

lat	Latitude
lon	Longitude
z	Value
circles	If not zero, use circles of this size.
squares	If not zero, use circles of this size
rectangles	If not zero, use circles of this size
hbars	If not zero, use circles of this size
vbars	If not zero, use circles of this size
perbars	If not zero, use circles of this size
parbars	If not zero, use circles of this size
levels	Levels used for determining symbols size
nlevels	Number of levels
colors	Colors to use
white	Logical, use white for lowest level if TRUE
n	Number of points used to make a circle (?)
maxcol	maxcolor?
digits	??
label.location	Where to put legend
labels	Labels for legend
fill.circles	Should circles be filled?
density	Density of shading when applicable
angle	Slant of shading
rotate	Should text (??) be rotated?
minsym	minimum value for a symbol to be drawn?
label.resolution	Number of digits in label???
col	Colors to use
labels.only	TRUE when labels/legend is added in a sperate call
open.circles	Should circles be open??
lwd	Line width of symbols
border	Should a border be drawn on the symbol
bordercol	Color for border if drawn

Value

No value returned, utility lies in side effect off adding colored symbols to existing plot, generally used as internal function in geosymbols.
