What ? ------ We are pleased to announce version 0.0.6 of littler What's new ? ------------ This version includes a bug fix or two as well as a number of small enhancements to the documentation. For OS X and the r/R confusion, our recommended suggestion is to call configure using either the --program-suffix=X or --program-prefix=Y option to have the binary and manual

Hello list, I'm having some difficulty getting rJava to load in littler. Even after a R CMD javareconf and a reinstall of littler, I get this: jlaing at xenon:~$ r -e "require(rJava)" Loading required package: rJava Loading required package: methods Error : .onLoad failed in loadNamespace() for 'rJava', details: call: dyn.load(file, DLLpath = DLLpath, ...) error: unable

Hi, I've been using r (the little, but sweet one!), and recently found out about the magic argv vector of the rest of arguments passed to it. How can we process an argument that represents elements of a vector: $ r littler_ex.R 14 '3, 2' Error in ff * ss : non-numeric argument to binary operator where: ,-----[ cat ~/scripts/R/littler_ex.R ] | ff <- as.numeric(argv[1]) | ss

Hi, how can I use R in a pipline like this $ ./generate-data | R --script-file=Script.R | ./further-analyse-data > result.dat Assume a column based output of ./generate-data, e.g. something like: 1 1 1 2 4 8 3 9 27 4 16 64 The R commands that process the data should come from Script.R and should print to stdout (Script.R could for example calculate the square of every entry or calculate

Hi. I would like to know how to start an embedded R session, and avoid datasets and the standard library packages to be loaded on startup. I've been looking at littler's code (so this is partly a question to Dirk Eddelbuettel...): > /* We don't require() default packages upon startup; rather, we > * set up delayedAssign's instead. see autoloads(). >

Hi, I'm trying to write a series of pipes using littler, and I get the following behaviour: Sorry if I'm just doing something witless, I'm new to R. I'm using the latest versions from debian testing (2.4.0 and 0.0.8). $ r -e 'a<-dget(file=stdin()); print(a)' ?list(a=2) Segmentation fault In R itself this works: > dget(file=stdin()) ?list(a=2) $a [1] 2 As do (from

Dear R folks, I have several data sets I want to process automatically using R. I found littler [1] and thought this will do the trick. 1. Read in data file to a data frame using `scan()`. 2. Do linear regression. 3. Write the data and the coefficients back to a file. #!/usr/bin/env r if (is.null(argv) | length(argv)!=1) { cat("Usage:

Dear R folks, wanting to compare different implementations of a solution I want to script it to iterate over the different implementations. Is there a way to do this in the R shell/command line? $ more /tmp/iterf.r f1 <- function(n = 100000, l = 100000) { z = n + l } f2 <- function(n = 100000,

Hello, I have this script which will be invoked as Rscript a.r < a.r a.r follows #!/usr/bin/Rscript --vanilla f=file("stdin") while(TRUE){ y=readLines(f,n=1,warn=TRUE) if(length(y)==0) break else print(y) } But it only reads one line from a.r How can I read line by line from standard input? Thank you Saptarshi

Hi, This code used to work well until a few months ago (I haven't used it since), but now it's giving this: ---<--------------------cut here---------------start------------------->--- $ cat <<EOF | r - locs <- read.csv(list.files(pattern="ds_.+_.+\\.csv"), colClasses=c(rep("character", 2), "numeric", "character",

Hi, I'm not sure when this started occurring, but now I get: ---<--------------------cut here---------------start------------------->--- $ r -e 'quantile(rnorm(1e5))' Error in (function (name, package, ...) : autoloader did not find 'quantile.default' in 'stats' ---<--------------------cut here---------------end--------------------->--- I'm using

Hi, I'm trying to write R scripts using littler (under Debian), and was originally using the shebang line: #!/usr/bin/env r However this picks up any .RData file that happens to be lying around, which I find a little disturbing, because it means that the script may not behave the same way on successive invocations. If you drop the /usr/bin/env trick then #!/usr/bin/r --vanilla seems to

Those of you tracking R development will have noticed that we are moving towards using R as a scripting engine. (It is often overlooked as such.) Thus far INSTALL, REMOVE, SHLIB and massage-examples have been moved to R. Reasons: - it is platform-independent and needs no other tools installed. No need to worry about strange 'sh' variants (as on AIX and in the past on Mac OS X)

Hi, I had a quick question I was hoping someone might be able to answer, as my journey through the source code so far has not been very profitable. I have a command line program that embeds R, and the program works just fine when run from the command line. However, when I run the program as a job in the LSF cluster at my institute, the following error occurs: Fatal error: you must specify

Is this possible? For instance, I have a function that returns a vector length 3. In one statement I'd like to assign each element of the vector to different variables. Syntactically, I hoped this would work: c(x,y,z) <- myfun(); Thanks, -- Jeffrey Horner Computer Systems Analyst School of Medicine 615-322-8606 Department of Biostatistics Vanderbilt University

Hi Accesses the $new method for a class defined in a package fails if the methods package is not loaded. I have created a test package with the following single code file: newTest <- function() { cl <- get("someClass") cl$new } someClass <- setRefClass("someClass") (This is similar to code actually used in the testthat package.) If methods is not loaded,
