I think I've gotten my Emacs/Sweave/R system set up correctly, thanks to Vincent and Jim, but I haven't been successful getting my first document produced. I'm trying to use one of Friedrich Leisch's examples, http://www.ci.tuwien.ac.at/~leisch/Sweave/example-1.Snw. I cut and pasted the text into a document sweaveexample.Rnw in Emacs. It seemed to be processed successfully with R:

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

Evening all: I'm taking a little time to experiment with R, Sweave, and Miktex/LaTex but I've run up against some problems and -well- I hope that there are some on the list who might have some suggestions. This will be kind of wordy as I will include the complete files involved as I'm just not sure what I'm looking for. Apologies at the outset. I created the source file

Hi All, I've reproduced the example from Prof. Friedrich Leisch's webpage. When I write sweave("Example-1.Snw") OR sweave("Example-1.Rnw"), (yes, I renamed them). I get the following error: Writing to file example-1.tex Processing code chunks ... 1 : echo term verbatim Error: chunk 1 Error in library(ctest) : there is no package called 'ctest' Also while

In a paper I'm writing using Sweave, I make use of lattice graphics, but don't want to explicitly show (or explain) in the article text the print() wrapper I need in code chunks for the graphs to appear. I can solve this by including each chunk twice, with different options, as in <<ortho-xyplot1-code, keep.source=TRUE, eval=FALSE>>= library(nlme) library(lattice)

Dear Sweave and R aficionados, I am using R and Latex for many years, writing texts in greek. I tried to combine them with Sweave, but without any success. Could you provide me with any help? Usually my LaTeX files are like this iso-8859-7 encoded .tex file: http://costis.name/0various/lists/R/sweave/successful.greek.tex , which happily produces

Hi - I'm running R 1.8.1 (compiled from source) on Mac OS X 10.3 (Panther). I find that, if Apple's X11 application is not running, Sweave gives an error when it wants to create a pdf or eps figure. E.g., in the package's own example-1.Snw file a boxplot is created at chunk 2: <<fig=TRUE,echo=FALSE>>= boxplot(Ozone ~ Month, data = airquality) @ Normally this will create

Hello Given the following data for a data set called airquality. To identify the nature of the objects from the data set airquality example "Ozone" would it be best to use the command is. like is.character(airquality$Ozone) ....... I tried attributes(airquality$Ozone) but it came up null. Would there be a better way to identify these objects. Thanking you in advance for your

This seems to be due to changes made by Martin Maechler in 2008. Presumably this fixed something, but it escapes my memory. However, it seems to have broken the equivalence between within.list and within.data.frame, so now within.list <- within.data.frame does not suffice. The crux of the matter seems to be that both the following constructions work for data frames > aq <-

Dear Researches, I am using RF (in regression way) for analize several metrics extract from image. I am tuning RF setting a loop using different range of mtry, tree and nodesize using the lower value of MSE-OOB mtry from 1 to 5 nodesize from1 to 10 tree from 1 to 500 using this paper as refery Palmer, D. S., O'Boyle, N. M., Glen, R. C., & Mitchell, J. B. O. (2007). Random Forest Models

Dear R-devel list, I realized that removing a predictor in lm through the "-"'s operator in formula() does not affect the complete cases that are considered. A minimal example is: summary(lm(Wind ~ ., data = airquality)) # 42 observations deleted due to missingness summary(lm(Wind ~ . - Ozone, data = airquality)) # still 42 observations deleted due to missingness, even if only 7

The function 'regsubsets' appears to calculate a BIC value that is different from that returned by the function 'BIC'. The latter is explained in the documentation, but I can't find an expression for the statistic returned by 'regsubsets'. Incidentally, both of these differ from the BIC that is given in Ramsey and Schafer's, The Statistical Sleuth. I assume

The following three functions are designed to make manipulation of dataframes easier. I won't write detailed docs just now, but if you follow the example below, you should get the general picture. Comments are welcome, esp. re. naming conventions. Note that these functions are definitely not portable to S because they rely on R's scoping rules. Not that difficult to fix, though: The nm

Hi, I'm new at this, I'm very confused, and I think I'm missing something important here. In our pet example we have this: > fm <- lme(Orthodont) > plot(Orthodont) > plot(augPred(fm, level = 0:1)) which gives us a trellis plot with the females above the males, starting with "F03", "F04", "F11", "F06", etc. I thought the point of

Hi, I seem to be facing a strange problem when I use Sweave for creating a LaTeX document of the R lme() output --- The EPS and PDF figure files get created, but are empty. I have attached a reproducible example below (taken from the R lme() help example). ------------------------------------------------------------------------------------ \documentclass[a4paper,10pt]{article}

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
