grid.pack {grid} | R Documentation |
This function, together with grid.frame
is part of a
GUI-builder-like interface to constructing graphical images.
The idea is that you create a frame with grid.frame
then
use this function to pack objects into the frame.
grid.pack(frame, grob, grob.name="", draw=TRUE, side=NULL, row=NULL, row.before=NULL, row.after=NULL, col=NULL, col.before=NULL, col.after=NULL, width=NULL, height=NULL, force.width=FALSE, force.height=FALSE, border=NULL)
frame |
An object of class frame , typically the output
from a call to grid.frame . |
grob |
An object of class grob . The object to be
packed. |
grob.name |
The name of the grob within the frame. This is crucial if you intend to access the object again, for example, to edit it. |
draw |
A boolean indicating whether the output should be updated. |
side |
One of "left" , "top" , "right" ,
"bottom" to indicate which side to pack the object on. |
row |
Which row to add the object to. Must be between 1 and
the-number-of-rows-currently-in-the-frame + 1, or NULL in
which case the object occupies all rows. |
row.before |
Add the object to a new row just before this row. |
row.after |
Add the object to a new row just after this row. |
col |
Which col to add the object to. Must be between 1 and
the-number-of-cols-currently-in-the-frame + 1, or NULL in
which case the object occupies all cols. |
col.before |
Add the object to a new col just before this col. |
col.after |
Add the object to a new col just after this col. |
width |
Specifies the width of the column that the object is added to (rather than allowing the width to be taken from the object). |
height |
Specifies the height of the row that the object is added to (rather than allowing the height to be taken from the object). |
force.width |
A logical value indicating whether the width of
the column that the grob is being packed into should be EITHER the
width specified in the call to grid.pack OR the maximum of
that width and the pre-existing width. |
force.height |
A logical value indicating whether the height of
the column that the grob is being packed into should be EITHER the
height specified in the call to grid.pack OR the maximum of
that height and the pre-existing height. |
border |
A unit object of length 4 indicating the borders
around the object. |
This is (meant to be) a very flexible function. There are many different ways to specify where the new object is to be added relative to the objects already in the frame. The function checks that the specification is not self-contradictory.
NOTE that the width/height of the row/col that the object is added to
is taken from the object itself unless the width
/height
is specified.
None.
