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).
