...ding (suggesting that there is a `title.cex` parameter which can be set, when there really isn't). Regardless of whether we call it an "oddity" or what, I don't think it's controversial that this is misleading.

...hen I feed the function data transformed by reflected reciprocal > skewness( max(data) - 1/data ) ) #returns NaN The vector has no missing values (and if it did, I would get NA rather than NaN, and the function wouldn't return a number when I give it the raw data).

Using multcomp::glht() with Anova object
...39;s possible to use glht with an Anova object? (I guess I can get these same comparisons by re-doing the anova using aov() or lme(), since I don't need the Huynh-Feldt corrections in the post-hoc tests...but I am just curious if i can do the post-hocs directly on my Anova object.)

duplicated() with long vectors
...d." But I've tried running this with a high value of nmax given, and it still gives me the same problem. So far the only way I've figured out to get this duplicated()-like vector is to use a for loop going through one item at a time, but that takes about a minute to run.

Contrasts in mixed effects model: difference between differences
...or of the differences between coefficients (my understanding is that the standard error of the coefficients I would get from ranef(test)$Subject is not going to be exactly the same as the standard error reported for the fixed effect [Baayen, 2008:247]).

Contrasts for 2x4 interaction in mixed effects model
...r2:SecondFactorB" doesn't tell me how different 2B is from 1B, it tells me how different 2B is from 2A. Is there a straightforward way to code the contrasts so that the coefficients I get for the interaction terms do the comparisons I'm interested in?

Fitting a multinomial model to a multi-way factorial design with repeated measures: help on package and syntax
Dear all, I studied in tank prey fish behavior. Using the design described below (and R code), I want to test the effects of both habitat and predator (and interaction) on prey fish's vertical distribution, which was recorded (with repeated measures) as a categorical variable. I found that package mlogit might fit to my need but I don't know how to specify my complex design in the
