similar to: R for education research tutoral?

Everyone: If you work in Higher Education, in either an office of Institutional Research or an office Institutional Effectiveness, I'm keen to hear from you on how you use R, individually or with colleagues. Why do you use R? Is the cost savings an issue? Do you also maintain a license to more established packages (e.g., SPSS, SAS, or Minitab)? Are you encouraged (allowed?) to

Dear R-Devel, I have had it in my mind for some time now that a Task View related to R and education might be a good thing. There are currently 19 Task Views, covering a broad spectrum of general topics for which R may be used. The homepage lists 64 books related to R, and several of them have accompanying packages on CRAN. There is a wiki and a host of contributed documentation. We also have a

We've recently had a thread on beginners and FAQs and the like. I decided that it might be a good idea to offer a short list of on-line help pages that beginners should read. Goals: - the list short be short (I think mine is too long) - many of the commonest questions should find answers there (fairish) - I should have found the pages helpful myself (no question about that) - it's a

Martin Maechler <maechler@stat.math.ethz.ch> replied: well, the explantion isn't hard: look at seq.default :-) That's the "efficient cause", I was after the "final cause". That is, I wasn't asking "what is it

I'm in e-mail contact with a geochemist who maintains a well regarded geochemistry web site. He's drawing diagrams either with a Turbo Pascal program running in a DOS window or with Excel. I'm trying to persuade him that R would be a better choice. Something he's particularly keen on is ternary diagrams. I think he is talking about ternary phase diagrams, and if so, it looks as

I'm sorry for the way OT post, but here goes. I'm an informatics specialist, and R user. My wife is a secondary school maths teacher. My wife recently tried to explain to her class the link between education and potential salary, and I would love to be able to show this graphically, however, I cannot find any freely available data for this. Does anyone know of a suitable dataset,

Bringing up an old topic on a small technicality. In the help documentation on seq. Value: The result is of 'mode' '"integer"' if 'from' is (numerically equal to an) integer and 'by' is not specified. The arguement in seq specifying length also creates "double" which is not obvious in the wording, as "by" is not specified

A student is trying to cluster some data. Tree-building things seem to be pretty hopeless (we've tried most of the ones in R, I think). Multi-dimensional scaling produces somewhat tantalising results: things do clump together somewhat, but the clusters overlap a lot. I was wondering if these was an artefact of squeezing it down to 2D, and whether 3D might be better. So loc <-

I just got a G4 running MacOS 10.3 today, so I immediately downloaded R from CRAN. To my disappointment, it insists on installing in a fixed place and requires a root password to do so. University policy is that if your machine is on the net, you WON'T get root access nohow, unless you're a designated sysadmin, which I'm not. Is there any alternative to downloading a source

I have some data which records, amongst other things, age (recoded by me to be in months), and drug group (a factor). The drug group is a 2 digit number, but there is no numeric relationship, and only 50 of the possible groups occur So > asd <- read.table("asd.dat", header=TRUE) > asd$group <- as.factor(asd$group) > plot(age ~ group, data=asd) gives me a series of

A package I have written makes considerable use of external C code. There appear to be no problems building a Windows binary with the GNU C compiler, but now I would like to make the package available for other platforms. A stringent check of the code with the gcc options '-Wall -pedantic' flags many nested functions and variable-length arrays that are not allowed in ISO C. Is it

Hello all, I'd like to announce the availability of a mailing list for a newly-formed SIG (Special Interest Group) dedicated to using R for Discrete Choice Modelling. This list is intended for discussion of issues revolving around the design and analysis of Discrete Choice (aka Stated Choice, Stated Preference or Choice-Based Conjoint) experiments. While R has good infrastructure for

I have just used the RAqua.pkg to install R, and it doesn't work! I have Mac OS X 10.3, and the old version of R works OK, but the .pkg thing installed, and then when I double-click on the "StartR" application nothing happens. Nothing at all, no little icon bobbing up and down in the dock, just nothing. What have I done wrong? I didn't have to install the other packages

I have a "list" of character vectors. I'm trying to see if there is a way (in a single line, without a loop) to pull out the first element of all the vectors contained in the list. listOfVectors[1:length(listOfVectors][1] doesn't work. ========================== If you want more details.. Here is my listOfVectors which is called "uuu" >

I have some data on a moving vehicle where, amongst other things, it looks as though it would be informative to fit a model with the following structure: Z = B.Y + errorz Y = C.X + errorz The X variables are observed predictor variables; 6 of the variables look promising (on the basis of what they mean). The Z variables are observed response variables; there are 4 of them. There is a

I have found XLispStat's spinning plots illuminating. I'd like to do the same thing in R. A dozen or so probes with help, help.search, apropos haven't turned up anything, and I've even resorted to grepping through the entire R source distribution looking for 'spin.*plot', to no avail. Either the feature is called something else in R (what?), or it's in some other
