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

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

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 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

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 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'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

Could someone tell me the difference between igraph and igraph0? I searched the CRAN web site, but cannot find an explantion of the differences. Thanks, Alan [[alternative HTML version deleted]]

Hi, I'm trying to build a thesaurus that will sensible values for rare words. I suspect the best algorithm to use is k-means although I'm not sure about that -- I would have preferred a k dimensional space with a binary cluster in each dimension so a word can belong to 0..k clusters, but I digress... I can measure the strength of correlation between words fairly easily by counting

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

I have a data set that is comprised of, for simplicity, a vector of numbers that I want to march across in overlapping windows of say 10 values each, computing a couple of values for each window. Is there a vectorized way to do this, or do I truly need to resort to looping--I think so? Any other clever thoughts? Thanks, Sean [[alternative HTML version deleted]]

I'm running R2.0.1 under Solaris 2.9 on a SunBlade 100. When I installed it, I set things up to use the Sun compilers cc, CC, f95 with the options recommended in the installation and administration guide. Until today, no worries. With all this discussion about R GUIs I thought I'd give R Commander a go. The web page said to install a bunch of packages first, so I did >

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
