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

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

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 4 c g 4 4.4 > class(test$id) [1]

I examined the archives on this mailing list, which is where I got the entry for xinetd.conf, but apparently everyone else is succeeding where I have failed. So I would be grateful for any help.

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 pdf file: http://hannes.fedorapeople.org/leon2005.pdf My main question is now how could I introduce these two additional terms into the Likelihood

tl;dr: Why are named arguments discouraged in `[.data.frame`, `[<-.data.frame` and `[[.data.frame`?

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. I have tried to uninstall and reinstall

Dear all, I am running a mixed model using lmer. In order to obtain CI of individual coefficients I use mcmcsamp. However, I need advice which values that are most appropriate to present in result section of a paper. I have not used mixed models and lmer so much before so my question is probably very naive. However, to avoid to much problems with journal editors and referees addicted to
