Hallo, does a package for Matlab exist in R? If yes, where can I find it and how can I install it under R? Thanks, Corinna

Dear list, Using serialize it is possible to save the binary string representing an R object to a raw R vector. ## adapted from ?serialize x <- serialize(list(1,2,3), NULL) x I am looking for a way to capture the binary string that in normal use of graphics devices will be written to (most commonly) a file connection. jpeg(file = "test.jpg") plot(1:10) dev.off() In other

Dear R help list members, I am experiencing difficulty in trying to generate a subscript '2' in an axis label. Although I can get the '2' into a subscript using expression(), R then forces me to leave at least one space between the '2' and the following character. My label is supposed to read 'N2O concentration (ppm)', and the space between the '2' and

Dear list, Could someone enlighten me a bit on the exact format used for text help pages as I see them on Windows in the help/ folders of (compiled) package roots. When opening an example of these files in a text editor (?Bessel in GNU emacs), the file is displayed as follows: _^HB_^He_^Hs_^Hs_^He_^Hl_^H _^HF_^Hu_^Hn_^Hc_^Ht_^Hi_^Ho_^Hn_^Hs Bessel package:base

Dear list, I'm trying to embed OpenBUGS in an R package for use of it on 64-bit Linux. In order to get the CLI working one has to compile C code contained in $OpenBUGS/Manuals/CBugs.html (copied to say CBugs.c) using gcc -m32 -o bugs CBugs.c -ldl I put the OpenBUGS distribution in the ./inst subdirectory of the package root. Where should I now put the CBugs.c and how

What's really the problem with: > regexpr( '\.odt$', "xxxxYodt", perl=TRUE ) Warning: '\.' is an unrecognized escape in a character string Warning: unrecognized escape removed from "\.odt$" [1] 5 attr(,"match.length") [1] 4 I know that I could use: > regexpr( '[.]odt$', "xxxxYodt", perl=TRUE ) But it seems to me that

Hi friends, does anyone know how we can 'control' R from Visual Studio .NET? e.g. start R, send a set of commands, save the results and open the results using Visual Studio.

I have a data frame with three columns, one coded as a factor. I would like to separate my data out into separate data frames according to the factor level. Below is a simple example to illustrate. I can get R to return the data in the correct format but cannot work out how to get separate data frames. I am a newcommer to programming in R so am not sure what I am missing! Thanks, Emily

Hi, I have a series of return data, a and b are factors. I would like to build a matrix which contains each vector of "returns". I am thinking about something as following, but I guess there should be a sensible way of doing this. returns <- split(return, list(regimef, assetf)) cbind(returns[[1]], returns[[2]],...,returns[[n]]) Could anyone give me some advice? Many thanks. --

Dear Guru's, Is there a package (R of course) with programs for diagnostics - roc, sens , spec, kappa etc? Best wishes Fredrik L

Can someone direct me to an R function that properly computes standard errors of data obtained from a complex survery design, i.e. perform alnalyses similiar to those that can be performed with SUDAAN, particularly for a non-parametric one-way ANOVA, e.g. signed rank test? Thanks, John John Sorkin M.D., Ph.D. Chief, Biostatistics and Informatics Baltimore VA Medical Center GRECC, University of

Good afternoon! I'm trying to use the survey package to get a better point of view for my data, but i need some piece of advice: i have some data from a survey which has been stratified using 2 criteria: region(7 values), size of locality(5 values) Using the survey pakage how can i define in a correct way this design (taking into account all 4 strata not just one as in the Survey

Good morning, Does anyone know of a package or function to do a beta regression? Thanks, Walt Paczkowski _________________________________ Walter R. Paczkowski, Ph.D. Data Analytics Corp. 44 Hamilton Lane Plainsboro, NJ 08536 (V) 609-936-8999 (F) 609-936-3733

I have a column of words, for example "DOG" "DOOG" "GOD" "GOOD" "DOOR" ... and I am interested in creating a matrix that contains the string edit distances between each pair of words. I am this close -> ' ' <- to writing the algorithm myself (which will allow for different variations on the string edit rules, indels,

Dear R-list members, I have been a user of SPSS for a few years and quite new to R. I read the documentation and tried samples but I have some problems to obtain results for a logistic regression under R. The following SPSS script LOGISTIC REGRESSION vir /METHOD = FSTEP(LR) d007 d008 d009 d010 d011 d012 d013 d014 d015 d016 d017 d018 d069 d072 d073 /SAVE = PRED COOK SRESID

Dear HelpeRs, I'm very fond of Sweave and I use it as often as possible. It'a a pity I can't use it for larger projects or can I? For instance suppose I have three files file1.rnw, file2.rnw and file3.rnw with Sweave code. Working on file2.rnw I whould like to exclude file1.rnw and file3.rnw temporarily and joining all of them later. This amounts to a mechanism similar to using

Hi, for simply for troubleshooting purposes (e.g. making sure that --max-ppsize=N) is set, is there a way to query the pointer protection stack size from R? I tried to grep the source code and couldn't find anything, so I expect the answer is no. Thxs, Henrik

Dear R-helpers, I am planning a course on Statistical Computing and Computational Statistics for the Fall semester, aimed at first year Masters students in Statistics. Among the topics that I would like to cover are linear algebra related to least squares calculations, optimization and root-finding, numerical integration, Monte Carlo methods (possibly including MCMC), bootstrap, smoothing and

Hi, Cosmetic. Starting R with e.g. --max-ppsize=-10 produces the following warning: WARNING: '-max-ppsize' value is negative: ignored The name of the option displayed in the warning is incorrect. Could that be fixed? See src/main/CommandLineArgs.c (there are 3 places in that file where the name of this option needs to be adjusted). This is with current R-alpha. Thanks! H. --

L.S. Since some time there is a new r-project.org site as announced here: https://stat.ethz.ch/pipermail/r-announce/2015/000581.html The logo has changed on the site, but I fail to find a vector graphics file. For the previous logo I used to go to https://svn.r-project.org/R-dev-web/trunk/Logo/ Is there anything similar for the new logo? Many thanks in advance. Kind regards, Tobias --
