Programming objects in R
I am planning a project where an object-oriented approach would be appropriate, and for a number of reasons I would prefer using either Python or R. My problem at the moment is to find out how to do OO programming in R. Are there any introductory texts anywhere ?

Permutation test, grouped data
I am perfectly aware that this question is not an R question, at least not yet, but I have not succeeded in finding what I want in other ways, so ... What I am looking for are two algorithms, preferabley in Pascal, but other languages may do. For (a) systematic (complete) permutations for grouped data with unequal group sizes, and (b) random permutations for the same kind of data. I know

Agent-based social simulation and R
Do anyone know anything about the use of R for agent-based social simulation? It should be possible, and would be convenient for the simple reason that there are several nice packages containing useful stuff for SNA (Social Network Analysis). Information about packages, web sites, experienced persons in the field, etc. would be very welcome. Tom

Tranferring R results to word prosessors
I have just started looking at R, and are getting more and more irritated at myself for not having done that before. However, one of the things I have not found in the documentation is some way of preparing output from R for convenient formatting into something like MS Word. An example: If you use summary(lm(....)) you get nice output. However, if you try to paste that output into the word

I am surprised (and a little irritated)
I have started with using R on Windows, and I am really happy about the system. Now, one of my other ambitions is to learn how to use Linux, so yesterday I downloaded OpenSuse and installed that. The next problem was to try to use R with Linux. And there I met the wall. I've understood that RPM's are somewhat like installing programs on Windows, so that was downloaded and started

Running an R script from Delphi 7
Gentlepersons: A long time ago I used to be able to start R (version 2.6.1) from a Delphi 7 program and run a script by using a procedure like the following: function StartRAndWait (CommandLine : string) : Boolean; var Proc_info: TProcessInformation; Startinfo: TStartupInfo; ExitCode: longword; CreateOK : Boolean; begin Result := False; { Initialize the structures }

Transferring results from R to MS Word
R-users At the moment I am teaching a course on the use of R for data analysis. Part of course requirements involves the transfer of results from R to something that resembles the APA (American Psychological Associations) type tables to MS Word. Until now I have used the HTML function in the R2HTML library, with a call like this: HTML(summary(model1), file("clipboard",

Authoring a book
Me and some colleagues are planning to write a textbook together ("Statistics using R") where the target audience for the book is psychologists and students of psychology. We thought that it might be a good idea to use a Wiki when writing the text. Is that a good idea? Does anybody have any experience in that direction? What alternatives are there? The tool (Wiki) would have to be

Row percentages for a table object
I an stumbling on something that is probably very simple, but I cannot see the solution. I have an object generated by the table () function and want to recompute this table so each cell represents the percentage of the corresponding row sum. Of course a dedicated function can be written (which I have done), containing the necessary loops etc., but there should be a simpler way. I'd

Is R portable?
Recently I came across an interesting web site: http://portableapps.com/. The idea is simple, this is software that is possible to install and run on some type of USB memory, a stick or one of these hard disks. I can think of a number of situations where this could be handy. In addition memory sticks are getting cheaper and more powerful by the day. So: Is it possible to run R off one of

Latex editor recommendations
This question is not oriented towards R, but is posted here because I have the impression that there are at least some Latex users among the contributors. The question is: What editors for Latex are to be recommended? I have located one: http://www.latexeditor.org/ What other alternatives are there? I am (for the most part) using Windows XP. Tom

Problem with pointsizes in Graphics
Hello, I have a problem with the sizes of points on the screen (Code tested for some R versions on a Solaris system and also for Linux). Maybe it is best to start with an example: If I do a very simple plot using the character '.' for the points, e.g., n<-100; plot(0:n,0:n,pch='.',cex=1+(0:n)/20) then not all for all the points the horizontal and vertical dimensions are the

[Fwd: Re: Response to R across the university]
Well, I downloaded the install JGR package for Windows and that seemed to work fine, after the installation I ended up with a modified R window which looked nice and uncluttered. Which I like. Very much. On the other hand, I cannot see how to launch the thing again once I have closed that window. There is supposed to be a launcher somewhere (JGR.exe?), but I have not been able to find it.
