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",

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

Dear R-help, I am running a Mac under Sierra, with R version 3.4.2 and RStudio 1.1.383. When running head () or tail () on an object in a script using source (<script name>) nothing appears in the output file, but if I use these commands in the normal R window the normal output appears. What am I doing wrong? Tom Backer Johnsen University of Bergen Norway

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

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

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 ?

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

Tom: Supposse your Excel file is named "myExcelFile" Open myExcelFile and SaveAs "myExcelFile.csv" or "myExcelFile.txt" Then go to the RConsole and type: #Option # 1 mydata <- read.csv("PathTomyExcelFile.csv",header=T) mydata # You should be able to see your dataset in R # Option # 2 # If you saved your Excel file as text then you would do: mydata

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

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

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

Hello world; been using nut atop Debian GNU/Linux (sid) for about two years by now, my configuration broke as I upgraded the machine this morning (headin' for kernel 2.6 to have full support for the new GBE NIC included). I read through the UPGRADE.gz instructions provided with the Debian packages and tried to fix things according to the instructions pointed out there, but things still just

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

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 }

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

A few days ago there was a thread on calling R from Delphi to which there were several useful responses. Now I responded as well, with what I regard as a useful contribution. Shortly after that, I was not able to able to see the thread in my newsreader (Thunderbird). Suddenly, yesterday I could see the thread again, and now it has vanished, at least from my sight. Now. Is there an error

The other day I was looking into one of the classics in resampling, Eugene Edgington's "Randomization Tests". This type of test is simple to do in R with things like a simple correlation, the sample () function is perfect for the purpose. However, things are more complex if you have grouped data, like a one-way ANOVA. The reason is that you have to avoid the consideration of
