similar to: Wish for stripchart to handle pch %in% 21:25 with bg

Dear all, consider: ### x <- round(rnorm(50)) stripchart(x, pch = 21, col = "black", bg = "pink", method = "jitter") points(0.5, 1, pch = 21, col = "black", bg = "pink", cex = 2) ### Under R 2.9.0 the points produced by stripchart are not colored, while points() gives the desidered output (magnified here by cex). I found a simple workaround

Dear list, I would like to make a Sweave document that, for a given package, automatically inserts the graphical outputs obtained when runing the example code of high level plot functions. That is, for the "graphics" base package, something like this: http://pbil.univ-lyon1.fr/R/fichestd/tdr79.pdf For this, I need the list of high level plot functions of a given package. I have

Dear Rdev, in R 2.9.0 the doc of function stars() does not state that it returns invisibly the location of atomic graphs. This is a valuable information as it may help to set a value for the key.loc parameter of this function. My whish is just that the "value" section in stars.Rd should be documented. Best, Pr. Jean R. Lobry BTW, the URL:,

Dear all, I'm trying to produce two dotcharts side-by-side within a Sweave document. When I'm compiling this example: \documentclass{article} \begin{document} <<fig=T,width=8,height=4>>= par(mfrow = c(1, 2), cex = 0.7) for(i in 1:2) dotchart(1:10) @ <<fig=T,width=8,height=4>>= par(mfrow = c(1, 2), cex = 0.7) for(i in 1:2) hist(1:10) @

Dear list, I'm trying to understand the graphical parameters by a systematic exploration of the par() function (if you are interested by the result it's here http://pbil.univ-lyon1.fr/R/fichestd/tdr75.pdf, the comments are all in french but it's pure R code under Sweave). I have a problem with par(tmag) illustrated by the following code:

Dear useRs, by a circular diagram representation I mean what you will get by entering this at your R promt: pie(1:5) Nice to have R as a lingua franca :-) The folowing quote is from page 360 in this very interesting paper: @article{SpenceI2005, title = {No Humble Pie: The Origins and Usage of a Statistical Chart}, author = {Spence, I.}, journal = {Journal of Educational and

Dear R-devel, googling for the single letter R yields R-home page as the firt hit, which is extremly nice. By clicking on the figure you get the code of the "Winner of the R Homepage graphics competition 2004." By copy/pasting in your R console it doesn't work because it is impossible to install the mva package. This is my point. As documented in ONEWS the reason is simple:

Dear R-help, I'm using prop.test() to compute a confidence interval for a proportion under R version 2.4.1, as in: prop.test(x = 340, n = 400)$conf [1] 0.8103309 0.8827749 I have two questions: 1) from the source code my understanding is that the confidence interval is computed according to Wilson, E.B. (1927) Probable inference, the law of succession, and statistical inference. J. Am.

Dear R-help, I would like to include the documentation of an R function in an *.rnw document processed by Sweave. Because I'm sharing my *.rnw files with colleagues under Linux and Windows (I'm on Mac OS X), I would like a pure R solution. The naive approach doesn't work, because Sweaving this *.rnw file: -------- tmp.rnw -------- \documentclass{article} \begin{document}

Dear All, I'am looking for examples showing that correlation does not imply causality, the targeted audience consists of undergraduate students (their first year at the university but in the BioMathStat track).
