for loops and counters
I am trying to assign values to a vector (pvalue). Similar code works in C but not in R. What am I doing wrong? r <- pvalue <- 0 for(i in (1:(k-1))){ for(j in (i+1):k){ r <- r+1 tstat <- (means[i]-means[j])/rms pvalue[r] <- 2*(1-pt(abs(tstat),df)) } } Thank you. Peter B. -- Peter B.

manova
I am using rw0641 with Windows 98. In the help for aov it states that the formula can sepecify multiple responses for a "maov". The help doesn't give an example, Venables and Ripley 1997:381 doesn't either. It isn't mentioned in the scripts nor in the section R Complements nor in Rnotes. I tried aov(c(y1,y2,y3)~x) which seemed reasonable to me but doesn't work. How

Influence.measures
I am using rw0641 with Windows 98. To list just the influential repetitiones that result from "influence.measures", I am using the input result <- lm(y~x) and the code from the example in the help for "influence.measures" INFLM <- function(result){ inflm <- influence.measures(result) which(apply(inflm$is.inf,1,any)) } It works fine up to now with the

How to superimpose a histogram and density plot
NCSS has a nice plot of the histogram and density plot superimposed. The S-PLUS 4 Guide to Statistics on page 45 suggests the following code for a general purpose density plot for a vector named data iqd <- summary(data)[5]-summary(data)[2] plot(density(data,width=2*iqd),xlab="x",ylab="",type="l") Is it possible to superimpose the density plot on a histogram

rw0642
Among other computers, I am using rw0642 on an IBM 300GL with 32MB RAM and Windows98. 1. If after opening rw0642 the first command is to help such as "? par", when the help window is closed by clicking X in the upper right corner of the help window the following message is shown This program has performed an illegal operation and will be shut down.

Tukey.aov with split-plot designs
I am using R 1.1 with Redhat 6.2 and RW 1.001 with Win98 (the upkey doesn't work on my IBM either as has been previously reported by others). The function aov doesn't return either the residuals or the residual degrees of freedom for split-plot designs. If you use the following code from Baron and Li's "Notes on the use of R for psycology experiments and questionnaires"

postscript()
I am using RedHat 6.1, the R1.1.0 binary download, and an HP Deskjet 692C. For some time I have been trying unsuccessfully to integrate R postscript graphics in LaTex. I consulted the Bug Tracking System. In the preamble of the LaTex file (test.tex) I have placed the line \usepackage{graphicx,color} and I use \begin{figure}[htbp] \begin{center} \includegraphics[height=4in]{graphic1.ps}

lme
I am using rw0641. In my continuing quest to understand repeated measures analysis, I again return to lme. I exported the Potthoff and Roy data Orthodont.dat from S-PLUS 4.5 to avoid capture errors and ran the examples in the R help. I imported the data.frame with data <- read.table("Orthodont.dat",header=T) attach(data) and created the objects Orthodont.fit1 <-

covariance matrix of the regression coefficients
Greetings, Cohen, Cohen, West, and Aiken 2003 (Applied Multiple Regression-Correlation Analysis for the Behavioral Sciences, Third Edition) on page 273 state the covariance matrix of the regression coefficients is provided by standard programs for multiple regression, including SAS, SPSS, and SYSTAT. How can it be calculated with R. Thank you very much. pbm Peter B. Mandeville cel:

S-Poetry in R
Kjetil Halvorsen mentioned a book call "S-Poetry in R". I checked with amazon.com and Barnes and Noble but they don't have it listed. Can somebody please give me the complete reference and where it can be obtained. Suggestion: Might it be possible to put a list of the most important and new literature about R, S, and S+ which has a direct bearing on R in the Documentation section
