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

paired t-test. Need to rearrange data?
Dear all,
I have received some data arranged like this:
# original data
id <- rep(letters[1:6], each=2)
time <- as.factor(rep(1:2, 6))
y <- as.vector(replicate(6, c(rnorm(n=1, mean=1), rnorm(n=1, mean=2))))
test.data <- data.frame(id, time, y)
test.data
I would like to perform a paired t-test of the y-values at time=1
against those at time=2, with samples paired by their id. Is it

efficient way to make NAs of empty cells in a factor (or character)
Dear all,
I have some csv-files (originating from Excel-files) containing empty
cells. In my example file I have four variables of different classes,
each with some empty cells in the original csv-file:
> test <- read.csv2("test.csv", dec=".")
> test
id id2 x y
1 a 1 NA
2 b e NA 2.2
3 f 3 3.3

Access Violation
...a kernel to a client using tftpd-hpa, is there any way
to track down the source of the error message, "PXE-T02 Access violation"?
All the files in /tftpboot have root ownership and 644 permissions, and
this works fine if I use an etherboot-derived floppy to start the boot
process.

everyone else is succeeding where I have failed. So I would be grateful

Estimation of an GARCH model with conditional skewness and kurtosis
Hello,
I'm quite new to R but tried to learn as much as possible in the last
few months.
My problem is that I would like to estimate the model of Leon et al. (2005).
I have shortly summarised the most important equations in the following

My main question is now how could I introduce these two additional terms

Re: ARP Timeout
...se lines, the boot continued to its conclusion.
For some reason I cannot get an arp reply using the boot agent in either
of two motherboards. Maybe the problem is due to hardware, but not knowing
how arp works, I had assumed it is a software issue. Is there any way to
pin this down further?

named arguments discouraged in `[.data.frame` and `[<-.data.frame`
tl;dr:
Why are named arguments discouraged in `[.data.frame`, `[<-.data.frame` and `[[.data.frame`?
(because this question is of the kind 'why is R designed like this?', I though R-devel would be more appropriate than R-help)

SciViews-R_0.8-9 Console problem
Dear R users,
I successfully installed SciViews the other day. However, when I try to
run it now, the command/script window does not appear. Strange. Well,
actually I see a tendency to a script window (in the lower part of the
sciview window where it is suppose to be) during start up, but when the
program is entirely open, the script window is gone.

fixed effects following lmer and mcmcsamp - which to present?

I am running a mixed model using lmer. In order to obtain CI of

values that are most appropriate to present in result section of a
