similar to: \Sexpr{}

I'm trying to learn Sweave. So far things are going well with the chunks of code identified by << >>= But I'm having trouble with the in-line text use of \Sexpr. Here is a short example .Rnw file: \documentclass[12pt]{article} \usepackage[margin=1.25in]{geometry} \usepackage{graphicx} \usepackage{Sweave} \begin{document} <<test>>= pnorm(1) @ \Sexpr{2+6}

Dear All, Using odfWeave is working fine for me using code chunks <<...>>= ... @ But the inline \Sexpr{date()} is not evaluated and returns again \Sexpr{date()} instead of "Thu Apr 17 18:15:47 2008". What might be the reason for that, what do I have to look for? I'm using Windows XP, R 2.6.1, odfWeave_0.7.3 and OpenOffice 2.4. Session Info: R version 2.6.1

I have come across an apparent bug in the operation of Sweave. If I load the package R2HTML then execution of \Sexpr{} in an *.Rnw file no longer works. The \Sexpr{} code is simply written to the *.tex file. Below are my *.Rnw file, commands, and output. The Sweave file, Sweave-test-1_short.Rnw: % -*- mode: noweb; noweb-default-code-mode: R-mode; -*- \documentclass{article} \title{A Test

An Sweave file, 'test.Rnw': \documentclass{article} \title{Sweave minimal} \author{MK} \begin{document} \maketitle We try Sweave: <<1>>= data(airquality) summary(airquality) x <- airquality[1, 1] @ I try Sexpr: \Sexpr{x} We plot: \begin{center} <<2, fig=TRUE, echo=FALSE >>= boxplot(Ozone ~ Month, data = airquality) @ \end{center} \end{document} I check the

Hi all, I have two vectors (columns) called "efinal" and "efinal 2". I want to plot them on the same plot and "draw" a shaded area beween the two lines using function polygon I have tried all but I don ?t understand the polygon area, can you help me with examples? plot(efinal,type="l",ylim=range(min(efinal2),

Hey all, In order to test if a marker is a risk factor, I built two models (using cox proportional hazard model). One model included this marker, and the other is not. Then, I use R package risksetROC to test how much predictive value did the marker add to this model. I get two C statistics by analyzing the linear predictors of the two models into this package. The qustion is How to test if two

Dear List members, I really, like the feature that one can call R functions with mathematical expressions, e.g. curve(x^2, 0, 1) I wonder, how I can construct in a simple way a function like mycurve = function (expr) {...} such that that a call mycurve(x^2) has the same effect as the call curve(x^2, -100,100) Below is some code that works, but it seems much to complicated: it first

Yes, it's homework . . . delete now if desired . . . but I think it is an interesting problem. Running R 2.11.1, LaTeX on WinXP, via Sweave. A drop1() object from a glm() produces, as part of its output, a string that looks like this: <none> The trouble I run into is that running latex() on a drop1() object from glm() produces a string that looks like this in the generated .tex

I would like to split a string into words at its blanks but also to preserve all blanks. Example: c(" some words to split ") should become c(" ", "some", " ", " words", " ", "to" , " ", "split", " ") I was not able to achieve this via strsplit() . But I am not familiar with regular

Hello R-help list,   I am looking for way to toggle the case of the characters like a flip-flop; that is from ''Hello'' to "hELLO" or vice versa.   I know that there are a number of functions like casefold, tolower, toupper, etc. but these functions change the case in an uniform way.   Thanks in advance,   Antonio Rivero Ostoic         Antonio Rivero Ostoic PhD Student,

I have an R script that consists of a for loop that repeats a process for many different files. I want to process this parallely on machine with multiple cores, is there any package for it ? Thanks -- Sandeep R Patil [[alternative HTML version deleted]]

Dear all, I have got a very big SPSS dataframe and I would like to just import one or a few variables (the dataframe has got a lot of colums). I used the package foreign but I couldn't find anything in there for my problem. Thank you very much for your help in advance. Marion [[alternative HTML version deleted]]

HI, R-Users: I got a questions. have been struggling so long time.... I have this data: > m1$Year_Month 201009 201010 201011 201101 201102 > min(m1$Year_Month) 201009 I want to calculate the following two answers, how do I program it? > difference in Month????? [1] 0 1 2 4 5 >difference in Days????? 0 31 61 .... Thank you in advance!!! Tammy [[alternative

Hi I am testing a package, and after I make changes, I have to close R and open R again to load the new version (same version number) of the package I am working on. So my question: is there a function which removes a package, i.e library(myPackage) > Package is loaded unlibrary(myPackage) > package is not loaded any more Thanks, Rainer -- Rainer M. Krug, PhD (Conservation Ecology,

Hello, Someone (Erik) recently posted about putting text on a plot. That thread didn't help. I'd like to put text directly below the 'sub' text (with no gap). The code below is the best I can do. Note the large undesirable gap between 'sub' and 'test'. I'd like the word 'test' to be just below the top box() boarder (directly below 'sub'). year

Hi all, I'd like to plot the Real and Imaginary parts of some f(z) as two different surfaces in wireframe (the row/column axes are the real and imag axes). I know I can do it by, roughly speaking, something like plotz <- expand.grid(x={range of Re(z)}, y={range of Im(z), groups=1:2) plotz$func<-c(Re(f(z),Im(f(z)) wireframe(func~x*y,data=plotz,groups=groups) But that seems like a

Good Night I made different test to check normality and multinormality in my dataset, but I don´t know which test is better. To verify univariate normality I checked: shapiro.test, cvm.test, ad.test, lillie.test, sf.test or jaque.bera.test and To verify multivariate normal distribution I use mardia, mvShapiro.Test, mvsf, mshapiro.test, mvnorm.e. I have a dataset with almost 1000 data and 9

Dear All: I would like to know if there is plausible way to say to R to remove all elements in the memory but the sequence. I have a code which makes a loop, and what I want is after the programme has performed all the operation over every "i"th element, to remove all the objects, expect the sequence parameter. I included the option "rm(list=ls(all=TRUE))", but obviously that

Dear list memebers, I am stuck with using regular expressions. Imagine I have a vector of character strings like: test <- c('filename_1_def.pdf', 'filename_2_abc.pdf') How could I use regexpressions to extract only the 'def'/'abc' parts of these strings? Some try from my side yielded no results: testresults <-
