Dear all, There has been some time since I asked about interpolation in higher (>2) dimensions, and I must admit I failed to write a function to do this myself the last time, but eventually ended up doing it in MATLAB. I tried to translate the MATLAB code, but MATLAB code is so much more opaque than R (S) code, so I failed that too, mainly because I could only get one MATLAB session, I would

Hi, I have a problem with an external library on a previous R version. We've created our own package containing a mixture of C++ as well as R code which works fine under R 2.12.1. However, trying to install the very same package ZIP file on R 2.11.1 will issue an error when loading a library: > utils:::menuInstallLocal() package 'quasar' successfully unpacked and MD5 sums

Dear all, Is there a simple way to add a qqline to the Q-Q plot plot.lm() produces for which = 2? If not, I might write one, but how should this preferably be implemented? Make qqline() generic and add a qqline.lm() method? Add an argument to plot.lm()? Have plot.lm() output something invisibly that qqline() can chew directly? Have plot.lm() output something invisibly that abline() can chew?

Dear all, I have been away for a month, but some time ago, I noted something that was very surprising to me. I think this example illustrates it well: > test <- data.frame(col1 = c(1,2), col2=c(3, 4)) > test col1 col2 1 1 3 2 2 4 > apply(test, 1, function(x) browser()) Called from: FUN(newX[, i], ...) Browse[1]> x$col1 NULL Browse[1]> x[["col1"]] [1] 1

Dear all, I'm generally not a big fan of GUIs, but I have just discovered one thing where a GUI would be a nice thing: creating color palettes. I'm creating an "image", for transparencies for a lecture I'm giving, so this is going to look great... :-) What I'm out for, is to make green tones and red tones, and a relatively sharp break between them. This break will

A lot of people have expressed interest in combining math features with Markdown, but I am not aware of any real developments from these requests. I was looking around and toying with [ASCIIMathPHP](http:// www.jcphysics.com/ASCIIMath/) and integrated it with MultiMarkdown and my xhtml2latex XSLT transforms. You can include math as an inline formula by using a markup similar to inline

Full_Name: Paulo Ribeiro Version: 2.1-1 OS: Debian Linux Submission from: (NULL) (200.103.144.24) I'm using Sweave with tex4th to generate xhtml documents from documents created using Sweave which include \usepackage{Rd} in the preamble However there seems to be a problem with \Link defined in Rd.sty, since this is also defined in tex4ht.sty My workaround was to replace the lines with

Dear all, Me and the Garbage Collector doesn't understand each other... I'm on R-1.0.1 (I have requested an upgrade to the right local people), an osf1 system with an alphaev6 CPU. I have fair amounts of memory to use, but it seems to be used up pretty fast nevertheless. I'm now trying to see what the garbage collector does, I have inserted a gc(v=T) call at a spot in my code. I

I'd like to ask what you all would think of me upgrading the libvorbis doc from whatever version of DocBook it presently uses to DocBook 5.0. There are three good reasons: - It supports XML namespaces, so you can embed stuff like Scalable Vector Graphics and MathML right into your DocBook source. - DocBook 5.0 uses Relax NG Schemas. This is a far, far better specification language than

It's whatever was current release during March. I have no way of doing regression tests, nor determining which broke what. IMHO the kernel is a suspect too, and March was a lot of upgrades ago for F8. The target system (F8KDE) gets used for MYOB about once a week and printing invoices about once a month, it took awhile before we discovered the system was really broken, we had initially

Hello, I have been trying to rejoin a computer to a newly remade PDC on the same domain name using Samba 2.2.7 on RedHat 9. I get this error message everytime I try: Title: "Computer Name Changes" "The following error occurred attempting to join the domain "Quasar": Multiple connections to a server or shared resource by the same user, using more than one user name, are

Dear all, I've been struggling for days now with a piece of code that I have posted here before, that has a really obscure bug. I think I may have isolated it, but I have no idea what it is.... It might also be a bug in R I guess, as it seems that one or several of list elements are not passed when a function is called, but quite rarely. I have been hacking rather wildly on the histogram

Dear all, After looking at several packages I decided I would use R for my thesis work (we've even got a site license for S-plus), so I'm learning. I have run into a problem, and nobody on the house has a solution, so I'm wondering if anybody out there can help. I've got two functions of four variables, one outputs a scalar, the other an array, and I want to be able to give an

Hello! I have two matrices of equal dimension ll and lu that I want to do a ks.test on corresponding rows in these matrices (dim(ll) is [1] 101 100). If I do e.g. > ks.test(ll[50,],lu[50,]) just for testing, it displays a lot of numbers, and some more info: [116] -3.000000e-02 -4.000000e-02 -4.000000e-02 -3.000000e-02 -4.000000e-02 [121] -3.000000e-02 -4.000000e-02 -3.000000e-02 -2.000000e-02

Dear all, I'm making a system to create a star-chart, and I have encountered one of the intuitive and clearly thoughtful conventions that are so common in astronomy :-J... Well, the point being, I have to reverse the x-axis. I figured, I might just set xlim=rev(range(x)). Do e.g. > x <- 0:5 > y <- (0:5)^3 > plot(x, y) > plot(x, y, xlim=rev(range(x))) The problem is that here

Full_Name: Kjetil Kjernsmo Version: 1.0.0 OS: osf1 Submission from: (NULL) (129.240.28.227) Hello! I'm afraid I have another obscure bug. R has just crashed with a segmentation fault. This time, I have even failed to reproduce it, but fortunately, I have a core dump. It's at <URL:http://www.astro.uio.no/~kjetikj/tmp/core> The call I did was log10(quantile(chisqtests5M11001,

Dear all, Either I'm being totally blind now (as you know, the eyes are the first thing that is blinded :-)), or something is missing in "An Introduction to R". The section heading of section 5.7.1 is "Multiplication, inversion and solving linear equations", and since I was looking for the canonical way of inverting a matrix, this was the place to look. However, I found

Dear all, I started a large run this afternoon, and when I came back after dinner, three of five processes had stopped with the error message: Error in matrix(nullprofile, length(nullprofile), nprofiles) : Unimplemented feature in copyVector I have seen anything about this anywhere (and I don't know where to look...). As you might guess, I'm trying to make a matrix where the

Dear all, I have an image that I need to filter, and so I'm looking for a method to convolve it with a matrix. If I understood the docs for convolve correctly, it only works in 1D (and I have tried to convolve, it didn't look good). So, I wondered if anybody have implemented 2D convolution in R, or have any good advices to share (beyond having a look at mvfft), before I go hacking?

Dear all, I'm a bit concerned about underflow problems. Such problems typically occur when two almost equal numbers are subtracted. I was wondering if R has any mechanisms for warning users about potential problems, or if any policy has been developed? To check, I just did: > 1.0000000000000001 - 1 [1] 0 > 1.000000000000001 - 1 [1] 1.110223e-15 > 1.00000000000001 - 1 [1]
