Last night I sent the bug report below to r-help. I have since then looked at dhyper.c and found: if (NR < 0 || NB < 0 || n <= 0 || n > N) DOMAIN_ERROR; I changed 'n <= 0' to 'n < 0' and then dhyper worked as I wanted. Am I introducing some potentially dangerous behaviour by this change? Goran

I am using R 2.11.1 in a Microsoft Windows 7 environment.   I tried using WriteXLS, but get the message " In system(cmd) : perl not found"   What is the "easiest" way to write an R dataframe to Excel?  (I am familiar with WriteXLS, but I do not have PERL installed, and if not needed, do not wish to install it.)   I am also familiar with write.table, but if possible, wish to

Hello, Could someone tell me whether the spatial statistics module of Splus is worth the rather high price, or whether one could (with reasonable effort) carry out the same things using R and some of its contributed packages. Although we do have Splus (Windows and Unix), we definitely prefer to use R whenever feasible (both for research and teaching). Thanks for developing a superb

I'm going to use dhyper(x, m, n, k) to get a 95% coverage. Let me use an example to explain my problem: Suppose I have a urn containing 90 red and 10 black balls. Now I wanna remove 3 from the urn. By the following codes: m<-90;n<-10;k<-3; x<-0:3 dhyper(x,m,n,k) I can obtain the probability that 0,1,2,3 red balls will be removed. 0.000742115 0.025046382 0.247680891

My question is really to Robert and Ross (and also to Bill Venables and Dave Smith) -- but I thought that there might be wider interest in it. The "Notes on R" in the file Rnotes.tgz is copyrighted to the above authors -- can I make copies of it to distribute? I suspect that the intention of the authors is that Rnotes be as re-distributable as R itself. However there is no GNU license

I am using R 2.11.1 in a Microsoft Windows environment. Is there a way to load a package (e.g. the zoo package) using only "written code", not menus or mouse clicks? The "code" below code brings up the "Select One" [package] menu.  I just want to automatically load the "zoo package".  local({pkg <- select.list(sort(.packages(all.available =

I have a pdf file that I would like to parse into R: http://www.williams.edu/Registrar/geninfo/faculty.pdf For now, I open the file in Acrobat by hand, then save it "as text" and then use readLines(). That works fine but a) I am concerned that some information may be lost and b) I may be doing this a lot, so I would rather have R grab the information from the pdf file directly. So: is

Thanks very much Douglas for the pointer to nlm. Maybe the "Notes on R" maintainer can add at least a mention of nlm in the section on nonlinear fitting? I never did nonlinear fitting in S-Plus before, so I have nothing to unlearn, but I was hoping someone could show me how to do a least squares fit with nlm. example: x<-c(1,2,3,4,5,6) y<-.3*x^-.6 +.2 y<-y+rnorm(6,0,.01)

Dear all, I'm quite sure that this is a stupid question, but I'll ask anyway. I want to perform an ANCOVA with two continuous factors and three categorical factors. Plant population growth rate (GR) = dependent variable Seed reduction due to herbivory (SR) = continuous explanatory variable Herbivore species (HS, 2 levels) = categorical explanatory variable Population (Pop, 24 levels) =

Hello, Due to a recent change in the bridge code, we now need a way of knowing if a packet has been defragmented. The bridge code now checks on the packet size and drops packets that are too big for the output port. Defragmented packets will get refragmented later, so they shouldn't be dropped. I've been reading the defragmentation code and can't find an easy way of knowing if a

I have *not* tracked this bug very far because I hope someone who is more familiar with the glm/anova code will jump in. If one fits a glm model with an offset, the NULL deviance is incorrectly calculated (it is calculated without the offset). The means one can get examples where the model deviance is greater than the NULL deviance. Here is some example output, (without the data). >

Johannes Huesing sent a message to stat-lisp-news at stat.umn.edu regarding an article in Linux-Magazin (German) on statistical software for Linux. I enclose excerpts. Can anyone summarize what was said about R in the article? If there is a web site for the article I would appreciate learning of the URL. I must admit, though, the my abilities in German are much less impressive than the

I'm wondering how odds ratio is computed. I thought that it is (n11/n12)/(n21/n22), but it is not what fisher.test() computes.

It is not about "really arge total number of observations", but: set.seed(4711);tabs <- r2dtable(1e6, c(2, 2), c(2, 2)); A11 <- vapply(tabs, function(x) x[1, 1], numeric(1));table(A11) A11 0 1 2 166483 666853 166664 There are three possible matrices, and these come out in proportions 1:4:1, the one with all cells filled with ones being most common.

I am using read.table to import a text file within R.   There are several "errors" in my text file.  An "extra" quotation mark has inadvertently been included within a few text fields.   e.g. for a pipe (|) delimited text file, I have something similar to this:   1|7|30| "dog" 2|6|25| ""cat" 3|4|20|"" 4|5| 56| "mouse" 5|3|56|
