ISwR library
I am learning to use R using a book that uses examples from the ISwR library so I need to have that library. When I type library (ISwR), R says: Error in library(ISwR) : there is no package called 'ISwR' Do I need to install ISwR separately? How do I do this? Thanks! -- View this message in context: http://www.nabble.com/ISwR-library-tf3548959.html#a9907582 Sent from the R help mailing

simple save question
Hi, When I run the survfit function, I want to get the restricted mean value and the standard error also. I found out using the "print" function to do so, as shown below, print(km.fit,print.rmean=TRUE) Call: survfit(formula = Surv(diff, status) ~ 1, type = "kaplan-meier") records n.max n.start events *rmean *se(rmean) median 200.000

changing names of vectors in list or data.frame
When I combine separate vectors into one list, there are new names created. I'd like to change them to something more meaningful. Here are two examples using data(zelazo) from library(ISwR): > library(ISwR) > data(zelazo) > attach(zelazo) > zelazo $active [1] 9.00 9.50 9.75 10.00 13.00 9.50 $passive [1] 11.00 10.00 10.00 11.75 10.50 15.00 $none [1] 11.50 12.00 9.00

Matrix/Table col headings R 2.0.0
I have been looking at some 'table' examples in Peter Dalgaard's ISwR book, and I am confused by how to get right justification of my table headings when I use the tables() command. Compare the following: # Produces right justfified column names caff.marital=matrix(c(652,1537,598,242,36,46,38,21,218,327,106,67),nrow=3,byrow=T)

Zero inflated negat. binomial model
Dear R crew: I think I am in the right mailing list. I have a very simple dataset consisting of two variables: cestode intensity and chick size (defined as CAPI). Intensity is clearly overdispersed, with way too many zeroes. I'm interested in looking at the association between these two variables, i.e. how well does chick size predict tape intensity? I fit a zero inflated negat. binomial

Stat textbook recommendations?
Hello, I'm looking for a textbook that can explain some of the math behind the intro-to-intermediate stuff like ANOVA, multiple regression, non- parametric tests, etc. A little background: I took an intro stats course last year and would like to further my education. Being as that was the highest (and only) stats class the local community college offers, it looks like I'm on

Problem in loading all packages all at once
Hi All Please see the Rprofile file which i have modified as follows and after that when I start R then I see that R says to me "TRUE" for all the packages implying that all loaded at once. But when i try to use commands as simple as help("lm"), it doesnt work nor any of the menu "Packages" is not working. Although the regression using lm ( Y ~ X ) is working

Template for building .deb packages for missing libraries?
Greeting R debianites - There are a number of R libraries I need debianized (for Ubuntu Maverick systems, if it matters) -- ISwR, Hmisc, mosaic, mosaicManip, HSAUR2 -- which I couldn't find debian packages for. The structure of R libraries is so regular that I'm guessing surely there must be a template for creating debian packages for them, or maybe a set of instructions? Does

ISwR (PR#9204)
I wanted to install the ISwR package onto my Linux system and used the install.packages command but it returns the message that the package was not found at the repositories. So I tried to install locally adding the argument repos=NULL but it gave a non-zero exit status report and the package is not present on the system. I am a novice UNIX user and also new to R but I have followed the

use of predict() with confidence/prediction bands
To my understanding, a confidence interval typically covers a single valued parameter. In contrast, a confidence band covers an entire line with a band. In regression, it is quite common to construct confidence and prediction bands. I have found that many people are connecting individual confidence/prediction interval values produced with predict(object,sd.fit=T,type="conf/pred") and

pairwise.t.test vs t.test
Dear all, I am perplexed when trying to get the same results using pairwise.t.test and t.test. I'm using examples in the ISwR library, >attach(red.cell.folate) I can get the same result for pairwise.t.test and t.test when I set the variances to be non-equal, but not when they are assumed to be equal. Can anyone explain the differences, or what I'm doing wrong? Here's an example

NEWBIE: Help explaining use of lm()?
I'm attempting the heruclean task of teaching myself Introductory Statistics and R at the same time. I'm working through Peter Dalgaard's Introductory Statistics with R, but don't understand why the answer to one of the exercises works. I'm hoping someone will have the patience to explain the answer to me, both in the statistics and R areas. Exercise 6.1 says: The zelazo data

displaying sample size in boxplots
Hi, I was wondering if there is a ready made function or parameter for indicating the sample size in boxplots? Here's what I came up with so far: library(ISwR) data(energy) attach(energy) boxplot(expend~stature) sample.size <- tapply(expend, stature, length) sample.size <- paste("N=", sample.size, sep="") mtext(sample.size, at=1:length(unique(stature)), line=2,

no write access for help files
Hi   I'm using R v2.8 under Windows*) and I'm trying to install a new package (local zip file), but I get the message below. I followed some advice at http://cran.r-project.org/bin/windows/base/rw-FAQ.html (4.2 onwards), but to no avail. How can I tell R to save the help files to an alternative location? I don't have write access to the default location.   >

Q: calling par() in .First()
As a result of another thread here, I need to be sure that the function par(bg='white') has executed before I create a plot. The simplest thing seemed to put it in .Rprofile: .First <- function() { options(width=150) par(bg='white') } But now R complains at startup: Error in .First() : couldn't find function "par" I have confirmed that once R has started,
