I'm looking for some tutorial on S4. I only find the following one, which is not in English. Can somebody let me know if there is any introductory material? I'm very familiar with OO and C++. If there is some material that suits my background, it will be great. https://stat.ethz.ch/pipermail/r-help/2009-January/184108.html

Greetings, I usually read this mailing list through google groups (http://groups.google.com/group/r-help-archive), but when I opened the webpage this morning it said: "The group named r-help-archive has been removed because it violated Google's Terms Of Service." Is there an alternative website which uses a similar structure to google groups? I had a quick browse on the R Wiki

Hello R-users, Checking the archives, I recently came across this topic: "export tables to Excel files" (http://r.789695.n4.nabble.com/export-tables-to-Excel-files-td1565679.html#a1565679), and the following interesting references have been proposed: http://rwiki.sciviews.org/doku.php?id=tips:data-io:ms_windows

Dear R-help, I first thought that the empty set (for a vector) would be NULL. x <- c() x However, the documentation seems to make clear that there _many_ empty sets depending on the vector's mode, namely, numeric(0), character(0), logical(0), etc. This is borne out by y <- letters[1:3] z <- letters[4:6] intersect(y,z) which, of course, is non-NULL: is.null(character(0)) #

Hello Rusers, I have worked on a R Wiki page for solutions in exporting R graphs, especially, the often-asked questions: - How can I export R graphs in vectorized format (EMF) for inclusion in MS Word or OpenOffice outside of Windows? - What is the best solution(s) for post-editing/annotating R graphs. The page is at: http://wiki.r-project.org/rwiki/doku.php?id=tips:graphics-misc:export. I

Hi, I am wondering if some experienced users would help put the ready-to-run code of the examples in the manuals. It would help new users learn R faster by putting all the examples in an ready-to-run R script file. Can somebody help do so sometime and post the code along with the pdf manuals? http://cran.r-project.org/manuals.html Regards, Peng

Proposal That a new mailing list be established that pertains exclusively to R documentation. The purpose of the list would be to discuss weak sections of the documentation and establish fixes for those weak spots. Pro If it works, there would be better documentation. It would be an excellent opportunity for newish and/or less technical people to contribute to R. In some respects such people

Hi, I have to match names where names can be recorded with errors or additions. Now I am searching for a string search function which returns always the "closest" match. E.g. searching for "Washington" it should return only Washington but not Washington, D.C. But it also could be that the list contains only "Hamburg" but the record I am searching for is

Some examples in the help page are too long to be copied from screen. Could somebody let me know some easy way on how to extract the example to a file so that I can play with them?

Hola, es la primera lista en la que participo, espero no meter mucho la pata y aprender rápido, se ruega comprensión. Simplemente me gustaría saber la forma de importar datos desde un archivo ".sf3' de Statgraphics. Creo que ese es un programa bastante difundido, pero no lo tengo y en principio no quiero tenerlo porque no es libre. Pero encuentro referencias a todo (piInfo, Minitab,

Hi all, I have not been able to find an answer to what is a simple question: conaguaMexicoSub <- subset(conagua, unidad == "Jalapa", select = c(equipo,X101:X309)) This subset gives me all the rows from conagua where unidad is Jalapa. But, please, how do I get all the rows where unidad contents Jalapa? I've been looking at regex, but I didn't find how pass one to unidad

I don't find a function to print a string to file. Would somebody let me know what function I should use?

A friend of mine just got bitten by the fact that sweep() will happily sweep out a STATS vector of an arbitrary length -- even one whose length is not a divisor of any of the margins -- without complaining. I know the answer to this could be "well just don't do that", but it's easy to make a mistake in which margin you're sweeping ... What would R-core think of the

Hello, I am new at R. I am trying to see if R can work for me.
