Hello, I'm trying to get S4 dispatch on S3 "connection" objects. So I do : setOldClass( "connection" ) and then : setGeneric( "bling", function(object) standardGeneric( "bling" ) ) setMethod( "bling", "connection", function(object) cat( "gotcha ", as.integer(object), "\n" ) ) but I get : f <- file(

Hello, I very much enjoy "with" and "subset" semantics for data frames and was wondering if we could have something similar with split, basically by evaluating the second argument "with" the data frame : split.data.frame function(x, f, drop = FALSE, ...){ call <- match.call( ) fcall <- call( "with", data = call[["x"]],

Hi everybody, I would like to ask if it is possible using pdf function or some other to print plots in cycle such that every new plot is on new page. like this pdf(file="D:/Plot.pdf",width = 9.25,height=9.25, family="Helvetica",pointsize=8,bg="white") for (i in 1:10){ x <- seq(1,40,1) y <- 2*x+1+5*rnorm(length(x)) hist(y,freq = FALSE) plot(density(y)) }

Dear R helpers,   I am working on the scenario analysis pertaining to various interest rates. In this connection I need to form the various combinations as under :   Suppose I have two sets A = (a, b, c) and B = (x,y,z)   Then I can easily form the cominations as (ax, ay, az, bx, by, bz, cx, cy, cz)   However, if I have say 5 variables, then total no of possible combinations will be 3^5 = 243.

Hello, I have the following problem when trying to use rm: In a top level script file I have a loop iterating over some index. The loop is not contained within a function, so the scope of variables declared in the loop is global. Within this loop I generate several variables which should be removed at the end of each iteration. To do this, I wrote a function to clean up the workspace. An example

Hi, I am Linux Ubuntu 9.04 user. I'm using R-2.6. Actually, I am developing R package for reading/writing 3D images. I needed to use the R package Rcpp in order to make profit of available C/C++ codes. My problem is that my C code is not able to include the Rcpp.h In fact, when I run this command R CMD build rply, I got the following error message in the file

Hi, I am looking for a R package which is capable to process and analysis pictures of tissues (stained) in an automatic way. I had a look on biops and EBImage (Bioconductor) but they are not automatic... Did you already use/know a such package ? Thanks, - Martial _________________________________________________________________ Tchattez en direct en en vidéo avec vos amis !

Dear R-users, I'd like to perform arithmetic functions on 1000 files containing a 2000x2000 matrix. Can anyone advise?

Hello, I've written a brush for R for the SyntaxHighlighter JavaScript library. It allows you to display R code on a web page with the proper syntax highlighting. It's available here: http://demitri.com/code Comments and suggestions for improvement are welcome! Cheers, Demitri

Dear All, I have a correlation matrix say 'M' (4000x4000) for 4000 genes and I want to subset it to 'N' (190x190) for 190 genes. The list of those 190 genes are in variable 't'. So the idea is to read the names of genes from variable 't' and subset the matrix M accordingly. Any thoughts are welcome! Best Lee [[alternative HTML version deleted]]

Dear all, i am new in R. I am writing a review paper about batteries. However, i am interested in analyzing all the papers by keywords, author, references and year. This could be done by "refviz" a software, which is only running on windows machines and which is not free. So my question to you is, is it somehow possible to write a script that can do all of this work? And if yes, with

Hello, I recently bought a new Macbook Pro and installed R via a disk image from an older computer - it seems to work fine. I then installed the package "siar", tried to load it via the library command and received the following messages (note the "mvtnorm" package did not appear to load correctly): trying URL

Hello, I wrote a package, which in the NAMESPACE file exports functions like this: exportPattern("^\\rh") On R-2.8 (Linux, 64), upon loading the package I have the rh functions present. On R-2.10, Mac OS X, (32 bit), it builds, loads, but the functions are not loaded, i.e the only function is rhyper (which is not from my package). Is there something wrong with my package setup?

Good Day, I can understand that after indexing a single column in a matrix, R will return a vector instead of the single column. However, during the conversion to a vector, the column name is lost. I was wondering if it would be better to have R return a single column matrix (retaining the column name), instead of automatically converting to a vector. Users could use as.vector() to convert

Upon seeing RWM Jones article "Using mount-local API from C" I became curious because I thought there WAS a way to combine aspects of FUSE with the tools provided by libguestfs. So if I wanted to create my own filesystem using callbacks placed in the 'fuse_operations' struct (parameter to 'fuse_main()'), I could do so using guestfs. But after reading the article and
