similar to: R brush for SyntaxHighlighter

Hello, I apologise in advance for this question; I'm sure it is answered in the documentation or this mailing list many times, however the answer has eluded me. I'm trying to write a function where I don't want external variables to be scoped in from the parent environment. Given this function: test_func = function() { if (exists("kat") == FALSE) {

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 ?

Dear R-users, I'd like to perform arithmetic functions on 1000 files containing a 2000x2000 matrix. Can anyone advise? For example, File1 File2 Output 1 1 1 4 4 4 5 5 5 2 2 2 + 5 5 5 = 7 7 7 3 3 3 6 6 6 9 9 9 Muhammad -- Muhammad Rahiz | Doctoral Student in Regional Climate Modeling Climate Research

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]]

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?

Hello, I am trying to use a C++ library I have to read some data into R. I've gone over the "Writing R Extensions" page and some of the archives, but am left somewhat confused (and I'm still very new to R!). What I want to do is fairly simple. Given some parameters, I'd like to read a string of numbers from a proprietary binary file into an array. I have a C++

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"]],

Hello dear R community, *Background:* Since I see more and more R users who blog about R opening their blogs in WordPress.com, I contacted one of their workers asking if they could add Syntax highlight support for R. He replied to me saying that if there was a "Brush" for R, according to the format given here:

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 Help, is someone going to write a R/S language lexer for the Pygments Python syntax highlighter <http://pygments.org/>? As it is used now by Trac, Django, or the Python documentation tool Sphinx, the R community can apply it in Python-based Wikis like Moinmoin and others. Hans Werner

suppose I have some logical vector x <- as.logical(c(0,0,0,1,0,0,1,1,0)) x How would I make the words TRUE appear on the screen in a different color from the words FALSE?

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 dear R help members (and also Yihui and Romain), There are currently 28 R bloggers (out of the 117 R-bloggers<http://www.r-bloggers.com/>I know of) that are using wordpress.com for publishing their R code (and I suspect this number will increase with time). WordPress.com doesn't support R syntax highlighting, nor can it be embedded from other services (like gist

Dear all Is it possible to get basic colour highlighting for inputs and outputs in the R terminal? I am looking for something similar to what GUIs provide, such as JGR and (I think) the Windows R GUI: colouring all inputs in red, and all outputs in blue. All this in a colour-aware console (in my case, on Linux). I've been looking into xterm256 and highlight, but I am sofar unable to do with

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

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

Hello, I'm the maintainer of a syntax highlighting tool highlight.js[1]. Recently the Kaggle project has announced they wanted to sponsor the development of the R highlighting definition for it[2]. I wanted to drop a line about it here since I suspect this list has much more R programmers on it than our small discussion group :-). So if you're interested and don't mind touching a
