similar to: Re: [S] extracting a matrix from a data frame

The only references to this I can find searching the archives are to a student who asked in relation to his course work on a stats course. Promise I'm not doing that! I have a situation in which we want to test proportions against an expected proportion, binom.test() is great. I'd like to do some post hoc power tests (the x and n were beyond our control in the survey as all we could set

I'm working on Windoze XP and have for some time installed R in D:\R and upgraded my packages after installing the new version of R with a bit of code I think I got from the list: ip <- installed.packages(lib.loc = "d:\\R\\R-2.4.1\\library") ip <- ip[ip[,1]!="base" ,1] install.packages(ip) This time around that's produced some warning grumbles: Warning messages:

<headline>Short question</headline>: Do people have advice on debugging R programs running after CGIwithR inputting of data from forms? Is there a way of setting up fast local versions if your local machine has to be a windoze (2k) machine (R 2.1.0) and your server is a Debian, ssh shell only set up running R 1.8.0? Are there simple guides to ways of not having to invoke R each

I'll take a risk following Uwe's wonderful response to that advert. I'm looking for someone, perhaps particularly a stats student, who might want to do a piece of work with me on using R to present and analyse routine data that psychotherapists might submit on a cgi-bin interface and perhaps cross-referencing that against some largish referential data to which I have access.

v 2.0.1 (sooooh old!) on Win2k I think I know the answer to this but I can hope ... I have data for continuous variables (measures of residents) by a categorical variable in range (1,22), the units in which they live. I want to plot these data with a pair of boxplots one above another with same x-axis (1,22) using par(mfrow=c(2,1)) and then plotting first for the women then for the men.

I'm sure I'm being stupid so flame away... R2.2.1 on Windoze (boohoo) latest updates of packages. I'm exploring a dataset (land) with three variables looking at an narrowly unbalanced two group (GROUP) ANCOVA of a randomised controlled trial analysing endpoint score (SFQ.LOCF.ENDPOINT) entering the baseline score (SFQ.BASELINE) as covariate and the following work fine: > res.same

I am keen to look at Rcgi as I want to put up some simple bits of R to do prescribed tasks on HTML form input. Rweb is overkill and worryingly flexible for what I want and it sounds as if Rcgi is more what I need. However, I can't get any of the URLs I've found for it to work over the last few days. Does anyone have a recent copy they could Email me or a working URL for it? TIA,

Dear all, I am developing a small suite of cgi-bin programs on my server that help provide some things that statistical/psychometric beginners may find helpful and which are aren't widely available. Some early e.g.s are: http://www.psyctc.org/stats/R/multirater.html http://www.psyctc.org/stats/R/CSC1.html and I'll be adding more to http://www.psyctc.org/stats/ and some that will be

Just in case anyone else hits this. I just installed R 11.0 alongside R 10.1.0 (off my D: drive in D:\R\... but I think that's irrelevent) and all went well, I selected my nearest CRAN mirror (Bristol is the one I like) and getting the selection list seemed to take ages though it did come eventually. However, I then got an error message saying that R couldn't make contact on port 80. I

Dear R gurus, particularly those of generous M$ tolerance and diverse gifts and knowledge! I have an interesting challenge that I will end up crunching in R involving service usage by patients. Maybe I can do all of it in R but I can't see how yet. My situation is that our IT Department can give me loads of XLS files about patients one of our services have seen. The are one per patient

I am moving from windoze on a Dell laptop to Debian but I seem to have hit a snag for R. I managed to find the information to point an /etc/apt/sources.list entry at my local CRAN repository and have installed R 2.13.1 for squeeze from the Bristol UK repository. I installed a number of the additional R packages using synaptic which reported no errors but when I run my first

I may be being dopey, I surely am, but I'm baffled by this. I've been working, on and off for a few days in R version 2.13.0 (2011-04-13) i386-pc-mingw32/i386 (32-bit) working it through ESS. I've got a dataframe created a couple of days back, during the session: > dim(AllDat) [1] 27270 94 I came back this morning and misremembered my variables and thought I had a variable

The specific message is: "Warning: package 'spatial' in library '/usr/lib/R/library' will not be updated" and the number of libraries about which that's the complaint is now increasingly almost daily so clearly something is wrong. I'm working on a laptop on which I do the recommended Ubuntu updates daily. I done a standard installation of R 2.15.1 using

Hi, Many thanks to those of you who responded to my last post about Schafer's MI packages. I am really pleased to have access to them through R which, I have to say, is an amazing piece of software. I am only sorry that I haven't found it until now. But, to my question. Does anyone know if there is a package developed for evaluating clinical significance using Jacobson and Truax's,

Dear list, I was wondering if there is a function to plot league tables, sometimes also known as "caterpillar plots"? A league table is conceptually very similar to a box plot. One difference is that the inter-quartile ranges are not shown. If there isn't such a function a first attempt for a "selfmade" plot would be to tell boxplot not to plot boxes (sounds silly

I prefer to use R on a linux box and ultimately need things to end up there to serve things up using David Firth's excellent CGIwithR and apache, but one step at a time and I've installed 1.8.1 under win2k. Another question that I'm sure is simple: is there a simple way to find the list of installed libraries I had in my 1.7.1 installation and use that to drive install.packages?

I am running 2.2.3a-12.3 on Debian stable with Win2k machine and an XP machine on a small home network. I have only just started using printer support and seemed to have it fine with a postscript and a "raw" connection for the HP LJ5MP printer (with internal PS) working fine from W2k and WXP. Then I took the server down as I'll need another parallel port in it. Rebooted after

This has probably been addressed here, but I can't find it if it has, and it may be up on the R project homepage or the CRAN pages, but if so .... ... so sorry if this has been answered before: question is, can I upgrade to 1.8.1 under Debian stable (a.k.a. "Woody")? The deb packages in the CRAN archive are clearly for 1.8.0 and those in the "unstable" distro for
