littler usage
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])

New project: littler for GNU R
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

littler+dget+stdin -> segmentation fault
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:

littler: Use for batch processing of data sets: How to pass filename?
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.

When using method L-BFGS-B along with a parscale argument, should the

scripts with littler
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

concatenating factor from list
Hi,
I've run into a ridiculous problem I can't find any solutions for in the
archives or help pages:
data(barley)
cutYield <- with(barley, by(yield, variety, cut, breaks = c(0, 30, 60, 90)))
As in this example, I'm using 'by' to return a factor for each level of
another factor. The problem is that 'by' returns a list of the factors,
and I need all these factors

scripting/littler: How to call function named iteratively (`f1`, `f2`, …)?
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
}

setting R_LIBS
Hello,
I'm adding a private library tree in my home directory by adding this to
my ~/.Renviron:
R_LIBS="~/R/library:${R_LIBS}"
so that once in R:
R> cat(Sys.getenv("R_LIBS"), "\n")
~/R/library:/usr/local/lib/R/site-library:/usr/lib/R/site-library:/usr/lib/R/library
Is this the best way to proceed?

annotating an axis in bwplot (lattice)
Hi,
I'd like to add, say, the sample size for every group in a bwplot as a
parenthetical annotation to the axis. Here's a sketch:

require(Hmisc)
age <- sample(1:100, 1000, replace = TRUE)
sex <- gl(2, 8, 1000, c("Male", "Female"))

standardization of slot access
Hi,
I'm usually confused about when to use 'slot' or '@'. I've frequently
read that it's always preferable to use accessor functions, so I would
think the '@' operator should be avoided. However, ?slot contains the
following advise:
"Generally, the only reason to use the functional form rather than the
simpler operator is _because_ the slot name has to
