Move or Draw to a Specified Position

Grid has the notion of a current location. These functions sets that location.

Keywords
dplot
Usage
grid.move.to(x = 0, y = 0, default.units = "npc", name = NULL,
             draw = TRUE, vp = NULL)

moveToGrob(x = 0, y = 0, default.units = "npc", name = NULL, vp = NULL)

grid.line.to(x = 1, y = 1, default.units = "npc", arrow = NULL, name = NULL, gp = gpar(), draw = TRUE, vp = NULL)

lineToGrob(x = 1, y = 1, default.units = "npc", arrow = NULL, name = NULL, gp = gpar(), vp = NULL)

Arguments
x

A numeric value or a unit object specifying an x-value.

y

A numeric value or a unit object specifying a y-value.

default.units

A string indicating the default units to use if x or y are only given as numeric values.

arrow

A list describing arrow heads to place at either end of the line, as produced by the arrow function.

name

A character identifier.

draw

A logical value indicating whether graphics output should be produced.

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.

vp

A Grid viewport object (or NULL).

Details

Both functions create a move.to/line.to grob (a graphical object describing a move-to/line-to), but only grid.move.to/line.to() draws the move.to/line.to (and then only if draw is TRUE).

Value

A move.to/line.to grob. grid.move.to/line.to() returns the value invisibly.
