Dear All, I am a beginner creating R packages. I followed the Leisch (2009) tutorial and the document ?Writing R Extensions? to write an example. I installed R 2.12.2 (I also tried R2.13.2), the last version of Rtools and the recommended packages in a PC with Windows 7 Home Premium. I can run R CMD INSTALL linmod in the command prompt and the R CMD check linmod. The following outputs are

Dear useRs, I have some trouble with the calculation of Cook's distance in R. The formula for Cook's distance can be found for example here: http://en.wikipedia.org/wiki/Cook%27s_distance I tried to apply it in R: > y <- (1:400)^2 > x <- 1:100 > lm(y~x) -> linmod # just for the sake of a simple example >

I am reading Section 5 and 6 of http://cran.r-project.org/doc/contrib/Leisch-CreatingPackages.pdf It seems that I have to do the following two steps in order to make an R package. But when I am testing these package, these two steps will run many times, which may take a lot of time. So when I still develop the package, shall I always source('linmod.R') to test it. Once the code in

Hi there, I am stuck trying to solve what should be a fairly easy problem. I have a data frame that essentially consists of (ID, time as seqMonth, variable, value) and i want to find the regression coefficient of value vs time for each combination of ID and Variable. I have tried several approaches and none of them seems to work as i expected. For example, i have tried:

Dear R-Helpers Given a function like foo <- function(data,var1,var2,var3) { f <- formula(paste(var1,'~',paste(var2,var3,sep='+'),sep='')) linmod <- lm(f) return(linmod) } By typing foo(mydata,'a','b','c') I get the result of the linear model a~b+c. How can I rewrite the function so that the formula can be updated inside the function,

Hi, folks linmod=y~x+z summary(linmod) The summary of linmod shows the standard error of the coefficients. How can we get the sd of y and the robust standard errors in R? Thanks! [[alternative HTML version deleted]]

Hi, folks, As seen in the following codes: x1=rlnorm(10) x2=rlnorm(10,mean=2) y=rlnorm(10,mean=10)### Fake dataset linmod=lm(log(y)~log(x1)+log(x2)) After the regression, I would like to know the mean of y. Since log(y) is normal and y is lognormal, I need to know the mean and variance of log(y) first. I tried mean (y) and mean(linmod), but either one is what I want. Any tips? Thanks in

I'm guessing this is a FAQ but I can't find it and that it is probably not exclusive R related but relevant so I thought I'd ask: When I view the PDF output from Sweave (e.g. Example 1 from the author's web site at [1]) on a Linux system using the standard PDF viewer [2], the circles for the outliers in the plot [boxplot(Ozone ~ Month, data = airquality)] show up as the letter

Hi folks, I created a subset of a dataframe (i.e., selected only men): subdata <- subset(data,data$gender==1) After a residual diagnostic of a regression analysis, I detected three outliers: linmod <- lm(y ~ x, data=subdata) plot(linmod) Say, the cases 11,22, and 33 were outliers. Here comes the problem: When I want to exclude these three cases in a further regression analysis, - for

Forgive me if this is a trivial question, but I couldn't find it an answer in former forums. I'm trying to reproduce some SAS results where they set two parameters equal. For example: y = b1X1 + b2X2 + b1X3 Notice that the variables X1 and X3 both have the same slope and the intercept has been removed. How do I get an estimate of this regression model? I know how to remove the intercept

Hello, markdown (Python implementation) seems to render:  to <img src="pfad/und/eine" title="lange/url zum bild.jpg" alt="alternativer text"/> breaking the URL at the whitespace. AFAIK whitespaces are ok in URLs so why is it breaking up the URL here? Thanks, Florian -- I'm using an

Dear R-Help, I'm new to R and struggling with weighting data when I run regression. I've tried to use search to solve my problem but haven't found anything helpful so far. I (successfully) import data from SPSS (15) and try to run a linear regression on a subset of my data file where WEIGHT is the name of my weighting variable (numeric), e.g.: library(foreign)

Hi Folks, I'm trying to get rgl.Sweave to produce plots with transparency. However, it just seems to produce opaque plots when pdf is the output type. Perhaps this is a known issue? I'll just use .png in the meantime, but wanted to see about this, as I didn't see it in the documentation (though it's possible I missed it). Thanks, Allie \documentclass{article} \title {rgl

Hello i like to give a windows group (W2K3-AD) permissions to use a share read/write on a Samba domain member server. Therefore if have added the Samba server to the domain without problem and created a share like this: [bild] comment = Some Comment path = /data/bild admin users = root force user = smbuser force group = sambashare valid users = DOMAIN\w-user1

Dear useRs, I'm trying to use ggplot2 in Sweave (R 2.5.1). The plots use the alpha channel, so I need to use pdf version 1.4. Search the mailinglist archive I found two solutions: \SweaveOpts{echo = FALSE, pdf.version=1.4} and explicit writing to a pdf 1.4 file. The latter works but the first doesn't. Probably I'm doing something wrong (see the Rnw file below). The file tmp_tmp.pdf is

I'm using Sweave to generate LaTeX output from R. Thank-you very much for this capability. It is very useful. Could someone please tell me how to pass non-default graphics parameters from par() to the pdf driver when it is called by Sweave? (I need to change some of the margin defaults. ) Hoping there is an easy solution to this question, Anne York

Hello! I am struggling for quite some time with proper printing of local characters in pdf plot, via Sweave snippets in Rnw file. When I am working directly within R, all is fine and I can get local character properly, like: pdf('figs/fig-relativeEntropy0.pdf', h=6, w=6, encoding='CP1250') matplot(par[, c(3)], type='b', ylim=c(0,0.5), xaxt='n', pch=c(21),

Hello, Is there a way to control pointsize of pdf:s produced by Sweave? I would like to have the same pointsize from (not a working example) pdf(file="C:/temp/example.pdf", width=7, height=7, bg="white", pointsize=10) plot(1:10) etc.. dev.off() as \documentclass[a4paper]{article} \usepackage[latin1]{inputenc} \usepackage[finnish]{babel} \usepackage[T1]{fontenc}

Dear R-Users, I am using R for years now but recently I encounter a problem with the pdf-size of graphics generated with sweave. However, I am new in this forum. Hence, please don't hesitate if I am wrong here. I use a script which runs perfectly in R 2.11.1 and the pdf-size of the graphs is about 3 KB. Running the same script with R 2.13.1 the file size increases to 12 KB. I am using about

I'm having a problem with dotted lines (lty = 3) in the pdf output in documents generated with Sweave. In the displayed pdf, the dotted line does not show up and in the printed output, it is there but does not seem to respect the lwd argument, for example, it is very faint despite using lwd = 3. The dotted line is correct in a quartz window and if I save the Quartz window to a pdf and
