similar to: Re: text book on experimental design

I'll be teaching a graduate course on (the analysis of) experimental designs next year, using R. Does anyone know of a suitable textbook? (Venables and Ripley MASS Ch6 on Linear Models covers roughly the right material, but at a level that is way too difficult for my students.) Sorry if this has been asked before. I've looked through the archives and found Julian Faraway's book, but

There's something (probably a lot) missing in my understanding of plotmath. The LaTeX code for what I'm trying to produce is \log(-\log(\hat R)) My (probably hopeless) attempt at it uses nested group()s: expression(plain(log) * group("(", -plain(log)*group("(", \hat(R), ")"), ")")) Can anyone do it right for me, please? Thanks, Ted. Dr E.A.

I would like to do a logistic multiple regression on a binary variate, with what Genstat calls an offset, ie a regression variable with the coefficient constrained=1. I'm far from home and have Splus but not R here, but any information from either source would be very welcome. I'd hate to have to go back to using Genstat . . . Thanks, Ted. --------------- Dr E.A.

There appears to be a bug in the R xfig() driver. When I run a simple example, eg > data(InsectSprays) > boxplot(count ~ spray, data = InsectSprays, col = "lightgray") the boxplot is fine. Doing the same thing after > xfig(file='test.fig') and then opening in Xfig (ver3.2 patchlevel 2) on my Linux box produces boxplots where the boxes, although correctly shaded in,

I'm looking for something like Brian Ripley's glmmPQL that will handle multinomial data. Does anyone know of anything? Thanks, Ted. -- Dr E.A.

Hi again! Well, I just realised that I am running an *unstable* version of R (if such exists) from early January, that I picked up for some weird reason (the appearance of manova??). In fact the starting message is R : Copyright 2001, The R Development Core Team Version 1.3.0 Under development (unstable) (2001-01-22) I have been tried to reproduce the same example in R 1.2.3 for Windows

Hi there, I want to create plots with some kind of 'complex' axis labelling of the form $\dot{V}$ and integrate those plots into a LaTeX document. What is the best way to go? I've figured out, that the 'plotmath' commands are somewhat limited (at least I wasn't able to get the $\dot{V}$ generated) and that plots with 'plotmath'-axes wouldn't export

I am sorry about the problem caused by my first attempt at reporting a bug. This is a followup to my report PR#225, hopefully being more useful. By not I have a better understanding of the problems being reported. I wish to report one bug relating to plot character and to mention two other possible bugs (these may relate to differences between R and S) I have noticed with R. We have recently

Dear friends. Please see the program below and answer if it does simulate a population of 1.000.000 families, each with at max 20000 children (typical in Denmark, you know), constructed such that each family stops having children when more boys than girls are present ? Equal numbers of boys and girls are got in the population, according to the simulation, is that obvious ? ND <- NP <-

I have downloaded and tried to install JGR - Java GUI for R - Version 1.5. I followed all the instructions (at least in my best resolution) and installed Java latest version. R installation complete fine. Has anyone succeded in installing JGR on SuSE 10.3 ? In the following I hade detailed the failed installation, As root /i did the following: linux-Mimin:/usr/local/bin # ./R R version 2.6.0

As to the function"pnorm",the default degree of freedom(df) is infinite. I wanna know how to set the df as I want. Help on pnorm doesn't have df setting.The only choice are:"mean, sd, lower.tail, log.p",but no df. For instance: sample size=6 df=6-1=5 t value=9.143 I wanna to the corresponding p value by using function "pnorm". How can I do it? Thanks a lot

Dear All, Is there a conmand to calculate the multiplication of the elements in a vector? For example: a=c(1,2,3,4) I want to get 1*2*3*4=24. Because the dimension of the vector is high, I want to know there is a command for this task in R? Thank you so much!

Dear List, I want to let R calculate the time (run-time) it requires to run a self-written simulation function. I tried as follows: it enables me to see the starting and finishing time points. ############################# "sim.result" <- function(nsim, ...){ Starting <- date() ... # calculations # final.result <- ... # Output for display # cat("# of Iterations used
