grid.points: Draw Data Symbols

Description

These functions create and draw data symbols.

Usage

grid.points(x = stats::runif(10), y = stats::runif(10), pch = 1, size = unit(1, "char"), default.units = "native", name = NULL, gp = gpar(), draw = TRUE, vp = NULL) pointsGrob(x = stats::runif(10), y = stats::runif(10), pch = 1, size = unit(1, "char"), default.units = "native", name = NULL, gp = gpar(), vp = NULL)

Arguments

x
A numeric vector or unit object specifying x-values.
y
A numeric vector or unit object specifying y-values.
pch
A numeric or character vector indicating what sort of plotting symbol to use. See points for the interpretation of these values.
size
A unit object specifying the size of the plotting symbols.
default.units
A string indicating the default units to use if x or y are only given as numeric vectors.
name
A character identifier.
gp
An object of class gpar, typically the output from a call to the function gpar. This is basically a list of graphical parameter settings.
draw
A logical value indicating whether graphics output should be produced.
vp
A Grid viewport object (or NULL).

Value

A points grob. grid.points returns the value invisibly.

Details

Both functions create a points grob (a graphical object describing points), but only grid.points draws the points (and then only if draw is TRUE).
