loop question
Dear all,
I am trying to set up a list with 1:c objects each meant to capture the
coefficients for one coefficient and 100 replications. I receive the
following error message:
Error in betaboot[[p]] : subscript out of bounds.
My code is below. Where is my mistake?
Many thanks,
Thomas

Finding functions in uninstalled libraries
...e).
I think I've been told this before, but how do I search for a
function/keyword in libraries I don't yet have installed?
(ie. on the CRAN site I tried the search engines with "recode" etc., but
didn't pick up the car package this way)

Are there any suitable routines that perform factor analysis of categorical

Should I be worried?
I am only mentioning this as I suppose it may be a bug somewhere in
ENOSPC handling, so perhaps someone is interested in this report...

xts indexed with Date class
Hi
I see a changed behaviour in xts indexed on class Date in the latest
versions, versus 2.
It seems to be related to changes to/from daylight savings time,
happens those weekends.
Is it not intended that class Date be used like this, or is this new
behaviour incorrect?
Giles
Example:
> a<-as.Date(15423:15426)
> x<-xts(seq_along(a),a)
> print(x)

rollapply.zoo() with na.rm=TRUE
Hi.
I'm comparing output from rollapply.zoo, as produced by two versions
of R and package zoo. I'm illustrating with an example from a R-help
posting 'Zoo - bug ???' dated 2010-07-13.
My question is not about the first version, or the questions raised in
that posting, because the behaviour is as documented. I'm puzzled as
to why na.rm no longer is passed to mean, i.e. why

contr.sum, model summaries and `missing' information
Hi,
I have a dataset with a response variable and multiple factors with more
than two levels, which I have been fitting using lm() or glm(). In
these fits, I am generally more interested in deviations from the global
mean than I am in comparing to a "control" group, so I use contr.sum()
as the factor contrasts. I think I'm happy to interpret the
coefficients in the model summary

an info on 3d representation
Dear list,
sorry to waste your time. I downloaded R and I like it very much.
However, my main interest is in plotting 3D graphics form imported data
(points and lines in a 3d space). I imported data in a very elegant way
but I wasn't able to find in R something similar to the simple "splot"
function of WGNUplot (I don't need persp, image, contour: my values are

Xen 4.3 release planning proposal
Hello everyone! With the completion of our first few release candidates
for 4.2, it''s time to look forward and start planning for the 4.3
release. I''ve volunteered to step up and help coordinate the release
for this cycle.
The 4.2 release cycle this time has been nearly a year and a half.
One of the problems with having such a long release is that people who

matrix no longer "is" array in 2.0.1?
I have an S4 class which extends array and has other slots, and in upgrading
to 2.0.1 (from 1.9.1) I have encountered a change in behaviour. This causes
me some difficulties if I want to allow 2-dimensional arrays in the slot
(which I do).
The following (in 2.0.1) illustrates the point:

S4 group generic with additional argument
Dear R-help,
I am attempting to set the "Summary" group generic function
for my S4 class. Using the standard arguments, this is easy. The function
returns the result of the generic for every element in a list:
? setClass("TestClass", representation(elements =
"list"))
? tc <- new("TestClass", elements = list(a = 1:5, b =
6:20))

--max-vsize
Hi,
In both R 2.13 and the SVN trunk, I observe odd behaviour with the
--max-vsize command-line argument:
1. passing a largeish value (about 260M or greater) makes mem.limits()
report NA for the vsize limit; gc() continues to report a value...
2. ...but that value (and the actual limit) is wrong by a factor of 8.
I attach a patch for issue 2, lightly tested. I believe that fixing

introspective capabilities
Hi,
Is there any way, from R code, to perform introspection as to where
certain names acquired their values? The specific functionality I'm
looking for in this case is to be able to request my editor to view the
definition corresponding to a name in its original source location
(presuming for the moment that that location exists). Other
functionality that I'm looking for is to identify

how to not sort factors when plotting
Hello,
When making a graph, plot and boxplot automatically sort my factor
levels (y axis) into alphabetical order. Is there a way to make it
NOT do this? I've tried:
sort.by="none", sorted=FALSE, sort=FALSE, reorder=FALSE.
Thank you.

Linus "praise" for Xen
http://www.kerneltraffic.org/kernel-traffic/kt20031201_243.html
--- Relevant section ---
Nuno Silva mentioned:
The good people at Cambridge made a (very nice) VMM that exploits
ring0/1/3 to let one machine run various kernels independently (the
kernels need to be ported to the xen arch).
Xen itself executes in ring0 and the "guest" operating systems
execute in ring1.
