grid.move.to
Move or Draw to a Specified Position
Description
Grid has the notion of a current location. These functions sets that location.
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 |
arrow | A list describing arrow heads to place at either end of the line, as produced by the |
name | A character identifier. |
draw | A logical value indicating whether graphics output should be produced. |
gp | An object of class |
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.
