I have a probably very naive question about the R anova/aov functions: I've found in several text books with descriptions of anova procedures that, in nested anova (specifying the model "X~A/B", B being a factor specifying treatments, and A groups of samples within each treatment), the mean square for "among treatments" is divided by the mean square "within treatment

Hello R experts, I haven't found anything like the S function 'varcomp' as described in W.N. Venables & B.D. Ripley's 'Modern Applied Statistics ...' for R; does something comparable exist for R, or is planned for future releases? More generally, are there libraries with post-anova test procedures, like Student-Newman-Keuls? Or do those of you who frequently use

Hello R-Experts, 2 questions: does anybody have example functions for determining the power of, say, a t-test or a single factor anova with fixed or random factors? and: is there an implementation of Cochran's test for heterogeneity of variances (i.e., is there a frequency distribution of Cochran's C)? Many thanks for your attention ... Ulf (please CC: me, I'm not on the

Hello out there, in their "R Complements" to Modern Applied Statistics W. Venables and B. Ripley say that there is a lack of time series related functions in R compared to S plus. Looking at CRAN I didn't find much, too. As I have to learn something about +-basic ts analysis, e.g. spectral analysis, I would like to know whether somebody has developed a "unpublished" time

-----BEGIN PGP SIGNED MESSAGE----- ld.so Vulnerability A buffer overflow problem was reported on bugtraq affecting the ELF and a.out program loaders on Linux. This problem can possibly be exploited by malicious users to obtain root access. On Linux, programs linked against shared libraries execute some code contained in /lib/ld.so (for a.out binaries) or /lib/ld-linux.so (for ELF

Hi folks, I'm trying to call an R function (fisher.test) in my program for like a billion times! Though my program is in Python and I feel that using rpy2 to interface R to python doesn't give me satisfactory performance. So I looked into R code and found out that fisher.test is actually a wrapper around another function called fexact which is implemented in C. Using Cython I managed to

Excuse me, if the following is FAQ or nonsense, I'm new to R (and the list)! After trying to import a textfile of 184897 Bytes, R (v0.63.0 on Linux 2.0.35/DLD 5.4) gives the following error message: > read.table ("db.out") Error: heap memory (1953 Kb) exhausted [needed 150 Kb more] > Is there a possibility to increase

I noticed that congigure reported libpng as "not found" although a recent version exists. Further looking into this issue told me, that the test failed because the test from R.m4 AC_CHECK_LIB(png, png_create_write_struct, [ BITMAP_LIBS="${BITMAP_LIBS} -lpng -lz" AC_DEFINE(HAVE_PNG) ], , ${LIBS}) ], AC_MSG_RESULT([no])) ]) did

I have a similar question, I know about --vsize, but I use R under Emacs using ESS. I know there is an easy way to call R from ESS with command line options but I don't remember how. I can't find help on this in ESS documentation or in R documentation. Could someone please remind me how this is done. ------------------------------------ | Robert Denham | |

Dear All, I am using fexact.c on a C++ program I wrote. To minimize dependencies on other files (e.g., to not need to include R.h and ctest.h ---now I only include the R files Boolean.h, Constants.h, and Memory.h), I have re-written all declarations of Sints as ints and, what is potentially more serious, I have re-written the line (lines 329 and 330, in fexact.c on R-1.6.1) /* IMAX is the

I tried to build R-1.1.1 on my HP-UX 10.20 box. For this I installed gcc 2.95.2 and built g77 (version 2.95.2 19991024 (release)). Making R runs to the point, where shared libs are linked. There it reports: make[4]: Entering directory `/disk4/hoffmann/Work/rwork/src/library/ctest/src' gcc -I../../../../include -I/usr/local/include -fPIC -g -O2 -c

Hi! I am Marta Colombo, student in Mathematical Engineering at "Politecnico di Milano". For my master degree thesis I have to analyze some categorical data. My dataset is composed by 327 individuals and 16 variables. I am using Fisher exact test to test independence on IxJ contingency tables, but I have a problem with one variable. R gives me this error message: FEXACT error 7.

I am trying to get R 1.0 running on the Mac. The main target is MacX. Anyone else working on that? For the recent Macintosh system, I am trying to compile R using MachTen. The R core compiles and runs without any changes, using the Unix make files. The libraries give some problems, presumably due to handling of shared libraries. It seems I am missing something to link. Before I spend my time

Dear all, I’m having an awkward problem in R. When I write the command Fisher.test(school.data,workspace=2e+07), where school.data is the matrix corresponding to the data set, I get the error message: FEXACT error 7. LDSTP is too small for this problem. Try increasing the size of the workspace. Increasing the workspace: Fisher.test(school.data,workspace=1e+10), I

Dear helplist Many many thanks to everyone who helped me. The trick was to use tabulate() or, better, tab <- rep(0,50) names(tab) <- 1:50 tab[names(table(sleeps))] <- table(c) My original dataset was a list of 50 trees and a length 12 vector recording which tree a certain possum slept in on 12 nights.
