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

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

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

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

This group impresses me, so far I have been helped with all my questions within 24 hours. Thanks. Therefore another one. I am used to programs (such as STATA) where observations with missing values that are included in a model are simply ignored in the analysis. So far I have not been able to figure out how to deal with missing values in R and have solved the problem by deleting observations

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

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

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 ?

Dear Sirs. I am working with the R packages Hmisc and PredictABEL to make NRI estimates from my Cox models with and without a specific biomarker. According to Pencina et al (Statistics in Medicine 2010, DOI: 0.1002/sim.4085 ), a continuous/non-categorical NRI (NRI>0) is to be used when there are no obvious reason to categorize risk, such as the risk of future cardiovascular events in patients

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

Dear Alberto, There are fisheries people also in Europe using AD Model Builder (Denmark and England for instance), but you are probably right that it is more widespread in North America. There is also effort going on where people try to make assessment models written in ADMB callable from R. best regards, hans > think AD Model Builder is mainly used for fisheries assessment in North

Dear all, I got point data of trees. I was wondering if anybody has experience in searching the neighbors within a specified distance efficiently. X Y Z 99 34 65 98 35 29 98 34 28 99 33 33 98 32 23 99 33 21 99 33 22 99 32 24 99 30 23 ... What I want to do is : searching for the neighbors with a distance R for each tree & the neighbor must have a bigger Z.

Dear R users I use Windows XP, R2.5.1 (I have read the posting guide, I have contacted the package maintainer first, it is not homework). In a research project on renal cell carcinoma we want to compute Harrell's c index, with optimism correction, for a multivariate Cox regression and also for some univariate Cox models. For some of these univariate models I have encountered an error

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 }

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",

Dear all, I am trying to read in big amounts of data with scan. It's only one variable, numeric values, separated by tabs,.. and it's many of them. So I was thinking that I could use the skip option and read in 100000 values at a time - but skip doesn't work, probably because I don't have line breaks in the txt file. So any value specified for skip makes the scan function jump to

On upgrading my F28 to F29, I've found that R-core and a number of R packages: R-evaluate R-glue R-highr R-knitr R-magrittr R-markdown R-mime R-stringi R-stringr R-yaml are installed, although I only ever install R from source and always keep my Rs locally. So I don't use Fedora R rpms, but these were installed without my command. Something in texlive is doing this. A remedy is to
