aggregating along bins and bin-quantiles
Dear all,
I would like to aggregate a data frame (consisting of 2 columns - one
for the bins, say factors, and one for the values) along bins and
quantiles within the bins.
I have tried
aggregate(data.frame$values, list(bin = data.frame
$bin,Quantile=cut2(data.frame$bin,g=10)),sum)
but then the quantiles apply to the population as a whole and not the
individual bins. Upon this

Oja median
I discovered recently that the phrase "Oja median" produces no hits in
Jonathan Baron's very valuable R search engine. I found this surprising
since I've long regarded this idea as one of the more interesting notions
in the multivariate robustness literature. To begin to remedy this oversight
I wrote a bivariate version and then decided that writing a general p-variate

Two Noobie questions
1. I have a list of lm (linear model) objects. Is it possible to select,
through subscripts, a particular element (say, the intercept) from all the
models? I've tried something like this:
List[[1:length(list)]][1]
All members of the list are similar. My goal is to have a list of the
intercepts and lists of other estimated parameters. Is it better to convert
to a matrix? How to do this?

Hello All!
I have a question regarding the package RDCOMClient. I want to start an
Excel file with R and it works flawlessly except the fact, that Add-Ins are

Custom Alloca implementation
---Adding llvm-dev list to CC---
Hi Alberto,
Thanks for your prompt reply. Actually, I need this information(about total
allocation size and object structure) on runtime, so that is why I was
planning to encode this info and store it in the memory itself.

Udit

Custom Alloca implementation
Hello all,
In my project, I need to allocate an extra 4 Bytes in every Alloca
instruction. These additional bytes will be used to store the 'allocation
info'(like size and structure of the allocated object etc). Instead of
adding 4 bytes to the Alloca 'size' operand at every Alloca Instruction, I
was thinking to make this change at the level where Alloca gets converted
to machine

[LLVMdev] Duplicating a Basic Block

I had asked earlier from my another ID about duplicating a basic block, but
that server is down for moment.

[LLVMdev] ARM JIT support status?
Hi.
I am a little unclear about the ARM JIT support status. Is it working
as of LLVM 3.1? If not, is it on the roadmap for LLVM 3.2?
I am not currently interested in NEON support so if thats
unimplemented, thats fine.
thanks,

Help on reading multipe files in R
Hi,
How can I read multiple files(in a loop like manner) within a single code of R ? For example, I need to run the same code for different datasets (here list of companies) and since individual files are quite large, appending the files into one file is not a desirable option. Can this be done through a macro or sql kind of command?
Thanks and Regards,

Remus' Network Buffering
Hi,
I am trying to understand and change the network buffering that is being used by Remus, the HA solution present in Xen. From what i understood from reading the code, Remus calls the postsuspend method of the BufferedNIC after it suspends the domain that sends TC_PLUG_CHECKPOINT message and start the buffering and then calls the commit method of BufferedNIC after it gets the acknowledgement

Plotting multiple series of data
I'd like to plot data that's in the form of a table such as this:
1 2 4 6 8 12
a 10 11 12 14 15 30
b 2 3 3 4 5 5
c 1 1 2 2 3 3
Where the row headers are the results for different series of tests, and the
column headers are the x-values.
I'd like to plot this as a set of lines, one each for "a", "b", and "c". I
can rearrange the data as needed, but
