box-and-whisker plots based on summary not data
Hi,
Is it possible to produce box-and-whisker plots given that I have the
median, interquartile and 5/95th centile values, but not the data from
which they come? It seems that it ought to be possible to coerce bxp
to do what I want, but I can't quite see how.
Thanks,
Matthew

Vioplot / list help
Hi,
I have some data (lots of year,distance pairs), which I can
straightforwardly boxplot:
dists <- read.table("movedists.dat")
with(dists,plot(as.factor(V1),V2))
If I want to plot these data as violin plots using vioplot, this
approach doesn't work:
> with(dists,vioplot(as.factor(V1),V2))
Error in Summary.factor(c(1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, :

argument handling in boot.ci
Hi,
boot.ci fails to check if the "type" argument is valid or not. This
tripped me up when I had a script that called boot.ci(type="normal",...)
repeatedly - only later when I tried to do some further analysis did I
realise I'd got nothing useful back from boot.ci.
It strikes me that this behaviour is probably incorrect, and that
boot.ci should stop if the

str and class
In previous versions of the gnm package, the terms component of "gnm"
objects had a "classID" attribute. This caused problems when used with
str as the following simple example illustrates:
> x <- 1
> attr(x, "classID") <- "type1"
> str(x)
Class 'type1' Class 'type1' Class 'type1' Class 'type1' Class

R package RPMs for Fedora
Hi all,
Three months ago, I wrote to Martyn Plummer (to his Warwick email) and
offered my help to maintain and modernize this [1] rather updated
README, but received no response. Does anyone know how to reach him,
or maybe I should contact CRAN directly?

Home Theater Thing
I checked Best Buy again. The second system I recommended is in stock
at the Best Buy in Warwick. It's on sale for $353. :)

I'm thinking about getting out of Dodge today to unwind so if you pick
it up early today I can come up and help you install it and then just
come home later in the day.

Using matprod from array.c
Hi,
I was wondering if I could use the matprod function from array.c in my own C routine. I tried the following as a test
/* my_matprod.c */
# include <Rinternals.h> /* for REAL, SEXP etc */
# include <R_ext/Applic.h> /* array.c says need for dgemm */
/* following copied from array.c */
static void matprod(double *x, int nrx, int ncx,
double *y, int nry, int ncy, double *z)

Re: [R-SIG-Mac] NaN and linear algebra
No, blas/veclib is tested, so aprt this extreme case you should report
some other more commonly used cases in which something fails on OS X.
This will help us to work it out.
As said, I'll try some tests without using veclib and let you know.
I've fowarded this mail to r-devel, which seems to be the right place,
so for future msg on the subject please use r-devel.

storage.mode, C data types and speed
Hi,
I am trying to speed up part of an algorithm in which certain columns of a large matrix (X) are replaced by the element-wise product of a matrix (M) and a vector (v). In R, the code might be
X[, ind] <- M * v
I have written a small C routine to do this for me, but the timing depends on how I define the storage.mode of the objects in R and the data types in C, in a way which I don't

ZFS Boot for Solaris SPARC
Hi,
Searching this alias I can find a number of guides and scripts that
describe the configuration of Solaris to boot from a ZFS rootpool.
However, these guides appear to be Solaris 10 x86 specific.
Is the creation of a ZFS boot disk available for Solaris SPARC ?
If so, could you point me in the direction of where I can obtain details
of this new feature from.
Thanks and Regards,
Paul.

R-Forge > GitHub?
Re your point 3: Because you have managed to create a GitHub version of
your repository that is not a fork of https://github.com/rforge/ecdat, but
its own independent repository, contacting GitHub support might not be the
right way forward. Note that https://github.com/rforge is simply a
read-only mirror of the complete R-Forge repository (and at least to me it
is unclear of whether GitHub itself

If statements for vectors
Dear Sirs,
I am using both the Bioconductor adds on (Affy, AffyPLM,...) and the
'standard' R-package.
I am trying to select a list of genes which all have expression values below
a certain threshold.
I have done this by creating a vector which has 0s where the expression is
greater than the threshold and 1s where it is less than or equal to it.
Multiplying this vector by the expression

Outdated Document - DOMAIN-CONTROL.txt
Dear Sir
I been reading through your (?) samba-doc folder on Debian 2.2.
The document DOMAIN-CONTROL.txt is dated 1996 and updated
1998. It mentions that SAMBA cannot be a PDC. This is not the
case anymore isn't it?

standardized residuals (rstandard & plot.lm) (PR#8468)
This bug is not quite fixed - the example from my original report now =
works using R-2.2.1, but
plot(Uniform, 6)
does not. The bug is due to

g <- hatval/(1 - hatval) # Potential division by zero here #

Loading of namespace on load of .Rdata (was strange behaviour of load)
Last week Giovanni Parrinello posted a message asking why various packages were loaded when he loaded an .Rdata file. Brian Ripley replied saying he thought it was because the saved workspace contained a reference to the namespace of ipred. (Correspondence copied below).
This begs the question: how did the reference to the namespace of ipred come to be in the .Rdata file? Brian did say it is

liboggz and packets versus segments ...
I'm doing some work where narrowband speex audio capture is happening and
being written to file in the ogg container format. Later retrieval for
reading will occur too.
I've been using liboggz to do the file reading and writing and have
obviously come across some things I don't seem to follow or have just got
wrong.
I can happily generate an ogg file using liboggz with some test

using eval() with pre-built expression inside function
I'm trying to evaluate a pre-built expression using eval(), e.g.
dataset <- data.frame(y = runif(30, 50,100), x = gl(5, 6))
# one like this
mf <- expression(model.frame(y~x))
eval(mf, dataset, parent.frame())
# rather than this
eval(expression(model.frame(y~x)), dataset, parent.frame())
In the example above there is no problem, the problem comes when I try to do a similar thing
