Dear r-helpers, Does anyone have a straightforward example of putting together three unrelated (expect for a common y-axis) xyplot() figures in what would be in base graphics a par(mfrow = c(1, 3)) arrangement? _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400 Charlottesville, VA 22904-4400 Parcels: Room 102

Hi, Does anyone know how to do a coord_trans() in which the y-axis is tranformed into (for example) -1000/y?

Hi, I would like to use the effect() function (actually a slightly modified version of it) on the output of the lmer() function in the lme4 package. But the effects package requires the nlme pacvkage, which is incompatible with lme4. Workaround? ______________________________________________ Professor Michael Kubovy University of Virginia Department of Psychology for mail add: for FedEx or

Dear Friends, Here is an algorithm for finding concave hulls: http://get.dsi.uminho.pt/local/ Has anyone implemented such an algorithm in R?

Dear -r-helpers, I'm trying to get my students to use odfWeave. Windows users are having trouble. I would appreciate advice. Comment 1: Hello I have spent a while today trying to get odfWeave to be successful I installed the unzip and zip program but it has not changed the error message.I have copied the error message below but I am sure it is the one others have experienced. >

The following plot is a first approximation to what I need: *********************************** mu1 <- 0 mu2 <- 5 s <- 1 x <- seq(-2.5, 7.5, length = 41) y <- seq(-2.5, 2.5, length = 41) f <- function(x,y){ term1 <- 1/(2*pi*sqrt(s*s)) term2 <- -1/2 term3 <- (x - mu1)^2/s term4 <- (y - mu1)^2/s term5 <- (x - mu2)^2/s term1*(.5 * exp(term2*(term3 + term4)) + .5 *

Hi Dieter, No, because I'm looking for the CIs on the means of baLO of an additive model which has 20 cells, exactly as stated. Essentially I want to have the values of 'lower' and 'upper' to plug into xYplot when used in the form xYplot(Cbind(baLO,lower,upper) ~ bar | sub, groups = delta, data=e7). Thanks.

Dear R-helpers, It is not clear to me how you get measurement.error SD when you have a single dataset, and it is not clear to me how sensitive SIMEX is to errors in the estimates of measurement error. Could someone please point me to the relevant literature? _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400

hi, is there an option to calculate the 'within' & 'between' group variances for a simple ANOVA (aov) model (2 groups, 1 trait, normally distr.) ? or do I have to calculate them from the Sum Sq ? thanks for your time and greetings, gregor -- Gregor Rolshausen PhD Student; University of Freiburg, Germany e-mail: gregor.rolshausen at biologie.uni-freiburg.de tel. :

Hi Michael, with res.uc$conf you'll get the single configurations for each rater. You can use these to produce the plot you want to have.

Dear R-helpers, I wonder if you can give me advice about the best way to use help(). (1) If I type ?normal because I forgot the name dnorm() I get a long list of relevant pages. Getting to right page is laborious. (2) If I remember dnorm() and want to be reminded of the call, I also get a list of pages. Advice? It seems to me that if the output of help() listed base functions first, it
