grid.points {grid} | R Documentation |
These functions create and draw data symbols.
grid.points(x = runif(10), y = runif(10), pch = 1, size = unit(1, "char"), default.units = "native", name = NULL, gp=gpar(), draw = TRUE, vp = NULL) pointsGrob(x = runif(10), y = runif(10), pch = 1, size = unit(1, "char"), default.units = "native", name = NULL, gp=gpar(), vp = NULL)
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. |
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). |
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
).
A points grob. grid.points
returns the value invisibly.
