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.

"dev.new(height = 10, width = 10) " doesn't work neither. It produces a device
with a size of [ 5.760417, 5.750000]. My computer is a usual 14 inch thankpad
labtop. Is 5 ~ inches really the up limit of the size of the R graphic device
in computer screen? I doubt it.
