similar to: Frame from long to wide format

Hello All, I was wondering if it's possible to reshape data from long to wide in R without using a "timevar". I've pasted some sample data below along with some code. The data are sorted by Subject and Drug. I want to transpose the Drug variable into multiple columns in alphabetical order. My data have a variable called "RowNo" that functions almost like a

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

I am having a hard time understanding how to perform a "repeated measures" type of ANOVA with R. When reading the document found here: http://cran.r-project.org/doc/contrib/Lemon-kickstart/kr_repms.html I find that there is a reference to a function make.rm () that is supposed to rearrange a "one row per person" type of frame to a "one row per observation" type

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

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",

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear R-helpers, my data.frame is of the form x <- data.frame( f=gl(4,3), X=rep(0:2,4), p=c(.1,.2,.3)) x f X p 1 1 0 0.1 2 1 1 0.2 3 1 2 0.3 4 2 0 0.1 5 2 1 0.2 6 2 2 0.3 7 3 0 0.1 8 3 1 0.2 9 3 2 0.3 10 4 0 0.1 11 4 1 0.2 12 4 2 0.3 which tabulates some values p(X) for several factors f.

Hi Everyone, I am trying to understand the unstack() function but after struggling for two days, I have given up. More specifically, I am trying the exercises at the end of Chapter 1 of Data Analysis and Graphics Using R by Maindonald and Braun, 2nd ed. Exercise 18 (p. 41) asks to unstack the Rabbit data frame from the MASS package to get a certain data frame that is shown in the exercise.

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

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

Hello R users and developers, I have a general question about reshaping a wide data frame using the "reshape" command. I have a data frame consisting of 108 columns that I would like to convert to a long table and remove the metadata (embedded in the column names of the wide table) to new metadata columns in the long format. #example data frame. NOTE column names contain metadata::

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 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

Dear R users, I'm having some problems with the stack() and unstack() functions, and wondered if you could help. I have a large data frame (400 rows x 2000 columns), which I need to reduce to a single column of values (and therefore 800000 rows), so that I can use it in other operations (e.g., generating predictions from a GLM object). However, the problem I'm having can be reproduced

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 ?

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

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

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 }
