Draws the symbols of a collection

Description

Draws all the required symbols from a collection of them

Usage

symbology(
  collection,
  sym,
  x,
  y,
  xfac = 1,
  yfac = 1,
  xadj = 0,
  yadj = 0,
  col = NA,
  border = "black",
  density = NA,
  angle = 45,
  lty = par("lty"),
  lwd = par("lwd"),
  scol = border,
  slty = lty,
  slwd = lwd
)

Arguments

`collection`	a collection object (e.g. oufti)
`sym`	the name of the symbols in the collection
`x, y`	numeric vectors of coordinates where the object should be drawn.
`xfac`	the x size factor.
`yfac`	the y size factor.
`xadj`	value specifying the x adjustment of the drawing.
`yadj`	value specifying the y adjustment of the drawing.
`col`	the polygons background color. If density is specified with a positive value this gives the color of the shading lines.
`border`	the lines color.
`density`	the density of shading lines, in lines per inch. The default value of NULL means that no shading lines are drawn.
`angle`	the slope of shading lines, given as an angle in degrees (counter-clockwise)
`lty, lwd`	the border line type and width, see ?par for details.
`scol, slty, slwd`	the colour, type and width of the shading lines.

Examples

# Create a data frame for all the required information ----

a <- data.frame(name = c("ammonite", "marcassite",
                         "nodule.point", "ammonite"),
                x = c(1,3,5,1),
                y = c(1,3,5,5),
                col = c(NA, "grey90",
                        "grey50", "grey90"))

# Draw them all in a single line of code ----

plot.new()
plot.window(xlim = c(0,6), ylim = c(0, 6))
