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

[MacQueen, Don]

But:

> dev.new(height=10,width=10)
> dev.size('in')
[1] 10 10

Whereas

> dev.new(length=10,width=10)
> dev.size('in')
[1] 10  7

Obviously, because height was not specified, some default calculation was used to set the height. And length was ignored.

And thanks to Duncan Murdoch for pointing out that the correct arguments are height and width, not length and width.

And, yes, please send plain text email to R-help. Sending HTML email reduces the likelihood anyone will actually read your email.

    When I check the size of the plot region usingdev.size("in")a new plot region is produced and in the Rconsole I get[1] 5.333333 5.322917If 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,
