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...

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 <- c(argv[2]) | print(ff * ss) `----- Cheers, -- Seb

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.

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=...

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: auswert...

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/en...

Going on I tried to script that using the `r` from the package `littler` [1]. Unfortunately because of the required quotes "" for the command `source()` I am not able to expand the variable. $ for i in $(seq 2); do r -e "print($i)" ; done [1] 1 [1] 2 $ for i in $(seq 2); do r -e 'source("/tmp/iterf.r");...

Dear R experts: I am a bit stymied by how the argument picking-off works in R batch file usage. $ cat commandArgs.R cat(" Command Line Arguments were ", commandArgs(), "\n"); $ /usr/bin/R CMD BATCH commandArgs.R --args 1 2 3 $ /usr/bin/R --args 1 CMD BATCH commandArgs.R ... I am now getting into interactive mode ?! I guess it really is skipping the rest of the command line

Dear useRs, This is to announce that the maintainers of the various distributions have decided to provide "experimental" up-to-date versions of the following R related packages on Debian stable and Ubuntu (i386 and amd64 architectures): littler rkward python-rpy (not on Ubuntu Dapper) python-rpy-doc (not on Ubuntu Dapper) By "experimental" we mostly mean that support for these packages may remain somewhat of a moving target for some time.

summary: how to structure an R file such that it can be both 1. used as a script via, e.g., (from OS commandline) $ Rscript foo.r bar=baz 2. imported and called as a function via, e.g. (from R commandline) > source('./foo.r) > foo(bar='baz') ? I'm looking for the 'R equivalent' of how python supports this usecase. details: As discussed in the thread beginning

Hi (again), Another difficulty I'm having is creating a common function (foo, say) to share between two scripts. I've tried making a third file containing the function and then sourcing it with source ("foo.R"), but that only works if you run the script in the directory where "foo.R" is. (or if the scripts know where they're installed) The other solutions that

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)
