What ? ====== littler - Provides hash-bang (#!) capability for R (www.r-project.org) Why ? ===== GNU R, a language and environment for statistical computing and graphics, provides a wonderful system for 'programming with data' as well as interactive exploratory analysis, often involving graphs. Sometimes, however, simple scripts are desired. While GNU R can be used

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

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 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, Is this sufficient? if (.Machine$sizeof.pointer==4){ cat('32\n') } else { cat('64\n') } Or is it better to test something in R.version, say os? I'd like to use this to specify appropriate linker arguments when building the RMySQL windows package. Jeff -- http://biostat.mc.vanderbilt.edu/JeffreyHorner

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:

I was writing Rd documentation for a new package when I came across this issue. Here's the smallest example: > library(tools) > cat("\\examples{x <- '<%=rnorm(1)%>'}\n",file=file.path(tempdir(),'test.Rd')) > readLines(file.path(tempdir(),'test.Rd')) [1] "\\examples{x <- '<%=rnorm(1)%>'}" >

I'm currently working on embedding R into the Apache2 webserver (with some positive results...), but I'm struggling to identify the best way to expose the apache data and functions to R. A couple of thoughts: In light of the recent discussion on "S3/S4 classes performance comparson", I'm leaning toward implementing the interface with S3 style classes. I appreciate

A professor here at Vanderbilt sent me the following code. Each of the text strings should right justify against the center vertical bar, but because of font issues it doesn't. I understand that there are workarounds, but I was just curious if this was consistent across all platforms. On linux with R 2.7.1 and R-trunk (r46103), both acrobat reader 8 and kpdf render it incorrectly. How

In R-2-4-branch r39548, Rcons_vprintf is called from stdout_vfprintf when R_Outputfile is NULL. When called and output is greater than R_BUFSIZE, output is truncated to R_BUFSIZE.

Hello all, I've been working on a new R Graphics device that targets Adobe's Shockwave Flash format (SWF for short). It uses http://www.libming.org/ on the backend. Here are some example outputs so far: http://160.129.129.41/~hornerj/plots/ Once you click on the above, choose a directory like 'smooth' and then click on test.html to see a side-by-side comparison of the swf

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've been wondering why my no-optimization R-devel builds have been hanging during "building/updating package indices ...". I tracked it down with gdb to this line from do_basename in utils.c: while ( *(p = buf + strlen(buf) - 1) == fsp ) *p = '\0'; Now, imagine if your compiler places the variable fsp immediately before buf on the stack, and strlen(buf) is 0.

Byron, I just read your blog (statcomp.blogspot.com, linked from your other post) and rand across your idea of an R/Flash graphics device. I've also been giving this some thought because of this amazing interactive flash app: http://tools.google.com/gapminder and others from http://www.gapminder.org/. I would love more than anything to work on this. The only hitch is that I'm so

For those R user's who don't subscribe to R-sig-db and are having troubles with the latest RMySQL binary on CRAN, please read the email thread at the end of this message.

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
