plots: screwed up aspect ratio
This is a new problem: Old versions of R worked fine. I am not sure when
it got broken. I am posting here instead of bugs in case this is not a
true bug.
New vanilla plots (I mean I don't fool around with par() etc) are screwed
up in several ways:
- the tick marks are twice as long as they should be
- the gap between the end of the tick and the top of the numerical labels
is twice as big as

Aspect ratio and limits
Suppose I have the following data I want to scatterplot:
> xy
[,1] [,2]
[1,] 0 0
[2,] 21 4
I start up a graphics window and fire away:
> plot(xy)
- but because the graphics window is square, the aspect ratio is
wrong. So I add:
> plot(xy, asp=1)
- now the aspect ratio is correct, but the Y range is about -8 to 11,
whereas my data has a Y range of 0

Getting default aspect ratio from lattice
How can I get the value of the aspect ratio that is used in a lattice
plot? In a levelplot for instance, the native units per cm of my x and
y axes are different, and I need to know the aspect ratio so that I can
correctly plot vectors. I know how to set the aspect in a high-level
lattice function but I can't quite figure out how to get it. I would
like call to levelplot() without printing

Small utility to modify Theora file aspect ratio / frame rate / cropping
Hello,
I encoded a bunch of theora video files from my DVDs. I thought for a long
time that mplayer was broken because it displayed the aspect ratio wrong.
Then I found out that the aspect ratio I was specifying was supposed to be
the pixel aspect ratio, not the video aspect ratio. (This is extremely
confusing and I urge you to change the semantics of encoder_example. I also
urge you to check for

Obtaining the true aspect ratio for a lattice plot
I almost always supply my own aspect ratio when plotting using
lattice. When I plot these to pdf, I would like to specify pdf
dimensions that will result in minimal margins around the plot. In my
application, resorting to a pdf cropper after plotting is not an
option - I must do it in R. The problem is that I cannot determine
the correct aspect ratio for the overall plot (accounting

lattice: cloud: aspect ratio, labels, vertical lines
I am interested to know how to make for clouds:
- aspect ratio = 1
- labels attached to points
- vertical lines from the points to the x/y base plane
I tried:
t = c( 'A', 'B', 'C', 'D' )
x = c( 100, 0, 200, 100 )
y = c( 0, 100, 0, 100 )
z = c( 80, 0, 20, 40 )
q = data.frame( x, y, z )
rownames( q ) = t

aspect ratio ?
Can someone enlighten me on what the status is of aspect ratio in theora
is ?
The ti structure has aspect_num and _den values, which I assume give the
intended display aspect ratio (e.g. 4/3).
The sample files on the bittorrent seem to say both values are 0 for all
files. I'd think it should at least be made impossible to have a 0 as
the denominator.
The library doesn't check the

Plot's aspect ratio and pty
Dear All,
I've been playing with pty, and it seems it does not produce square
plots as it is expected to (or at least as I expect it to). Consider
this simple example:
par(pty="s"); plot(1:10, 1:10)
This should produce a square plot, right? Well, if you have a look at
the graph, it is not square! So, maybe the limits?
par(pty="s"); plot(1:10, 1:10, xlim = c(0,11),

Poor encoding quality with etheora and aspect ratio problem
Hello,
I wrote a theora video encoder based on etheora (and the examples
provided with it) for Processing IDE (processing.org). I have some
problem with the quality of encoded frames.
eg. http://poux.be/tmp/movie.ogg
And when I play the movie with mplayer or totem, the video resolution
is changed from 640x480 to 854x480 (when i use
ETHEORA_ASPECT_NORMAL in etheora_enc_setup). And if I try to

Graphic aspect ratio
Hi
I've been playing with a 3x2 graphics device using the default size as it
appears on screen. This has given me tall thin plots which I can resize by
dragging the window and increasing the window width. However I was wondering
if I can force R to produce square plots or set the actual aspect ratio. asp
seems to affect data units, not on-screen pixel units.
thanks

gpu scaling - aspect ratio issue
When I load an Infinity Engine game (in this case Baldur's Gate and Icewind Dale 2) I can't seem to get the aspect ratio to stick. If I set IWD2 to windowed it's fine, but if it's full screen it will either load as a window anyway or stick 1024x768 resolution into a 16:9 aspect ratio. I've fiddled with the nvidia control panel, but had no luck.

contourplot, xyplot, aspect ratio, mfrow
Hi,
I am gradually moving from the classical R plot functions to the library Lattice
I have some questions about contourplot () and its arguments:

the same distance on screen. This was obtained in the classical R plots with plot.default(x,y, asp=1,...) and then

setting par(srt) according to plot aspect ratio
How can I look up the aspect ratio of a plot, so I can use that to correctly
adjust the angle of text which is supposed to be parallel to a line in the
plot?
The following example code works for a 1:1 aspect ratio, but puts the text
at the wrong angle if the plot region is short and wide or tall and narrow.
I can't find a par() component containing the plot aspect ratio. It will

Aspect ratio question
Hi,
despite the warnings on the website ;-) I played with the current CVS
source of theora on Windows 2000 w/ Microsoft Visual C++. The codec and
the "experimental" example programs compiled fine. I also encoded a 33
MB MPEG2 (?) video (3 minute trailer) to a 14 MB .OGG using "mplayer -vo

ggplot aspect ratio
Is there a way to control the aspect ratio of plots using ggplot?
Specifically, I'm using the formula=a~b argument to produce a grid of
plots, but the overall width of the result seems to vary for reasons
that are obscure to me.
This affects not only the appearance of the plots but the amount of
space available for the title (which seems to be right justified

ggplot2, coord_equal and aspect ratio
Hi everyone, Hi Hadley,
I am a heavy user of coord_equal() in ggplot2 since most of my data is
spatial, on x,y coordinates. Everything works. However by enforcing an
aspect ratio of 1 for the plotting region, coord_equal() usually
wastes a lot of space if the region of interest is not a perfect square.
For example:
x=runif(10)
a=data.frame(x=x*3,y=x)
ggplot(data=a, aes(x=x,y=y)) +

[PATCH] Resize improvements (Multiple resize modes, better aspect ratio constraining)
Hi,
I have ported various improvements of Beryl's resize to Compiz:
- multiple resize modes (aside to the standard "normal" mode those are
"Stretch", "Outline" and "Filled Outline")
- better aspect ratio constraining (you now also can resize aspect
constrained windows from other edges than the lower right)
- avoiding of mouse pointer desynchronization

aspect ratio 1 and blank space
Hi,
I need to produce an ordinary scatter plot and it is vital that the aspect ratio equals 1.
I set the axis as:
plot(x, y, type="n", asp=1, ,ylim=c(-80,70),xlim=c(0,100)).
The problem is that I get some 'additional' blank plot area (basically, the lower bound of xlim becomes quite negative).
The xlim is not the range of the x-data, but I need the 0 there for further
