why the length and width of a plot region produced by the dev.new() function cannot be correctly
set?

Your test is all mangleed together. You failed in your duty to read the list
info and the Posting guide . NO HTML!
If I mean to produce a plot region with size setting
bydev.new(length=3,width=3)a plot region is produced, but the size is
[2.281250, 5.322917], as detected by the de.size function. If I
type:dev.new(length=10,width=10)I get a plot region of with the size of
[7.614583, 5.322917]. It seems that the width of the new plot region cannot be
set, and tt is always 5.322917. The length of the new plot region can be set,
but it is always smaller that the values I set.What do I miss? What is the
correct way of setting the dimension of the new plot region? I will be grateful
to any help.Best regards,
The size of the device is not the size of the plot region. You need to take
into account the margins. See ?par
Thank you, David.I have read the par() document. Clearly the size of the plot
region is smaller than or equal to the divice size. However, if I produce a
graphic device with dev.new (length, width) or other functions, I find the
largest width of the new device is always 5.3 inches whatever the values I
set, and the length of it is alway smaller than what I set.
The length and width aren't the first and second parameters for any
device, and length isn't a parameter at all. Try
dev.new(height = 10, width = 10)
and you should get a bigger device if it will fit on your screen. If it
won't fit, then you might get a smaller one, and you'll need to choose a
non-screen device such as png() or pdf() instead of the default device.

Could you tell me how to produce a graphic divice with correct size
that I set? I need this function because the graphic divice cannot
accomendate all of the graph I make with some of plot tools such as
ggtree. In ggtree plot, part of the tree tips label are invisible
(https://www.dropbox.com/s/87gyusx7ay1xxu8/tree.pdf?dl=0) even I set
"par(mar=rep(0,4))". So I think I must plot the tree on a larger graphic
device. Best regards.
