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 | numeric vector or unit object specifying x-values. |
y | numeric vector or unit object specifying y-values. |
pch | numeric or character vector indicating what sort of plotting symbol to use. See |
size | unit object specifying the size of the plotting symbols. |
default.units | string indicating the default units to use if |
name | character identifier. |
gp | an R object of class |
draw | logical indicating whether graphics output should be produced. |
vp | A Grid viewport object (or NULL). |
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
).
Value
A points grob
. grid.points
returns the value invisibly.
