stacking consecutive columns
I have a file, each column of which is a separate year, and each row of each column is mean precipitation for that month. Looks like this (except it goes back to 1964).

Aggregate data frame across columns
Folks,
I have a data frame with columns 200401, 200402, ..., 201207, 201208.
These represent years/months. What would be the best way to sum these columns by year? What about by quarter?
Thanks for your time,
KW

Initial values of the parameters of a garch-Model
Dear all,
I'm using R 2.8.1 under Windows Vista on a dual core 2,4 GhZ with 4 GB
of RAM.
I'm trying to reproduce a result out of "Analysis of Financial Time
Series" by Ruey Tsay.
In R I'm using the fGarch library.
After fitting a ar(3)-garch(1,1)-model
> model<-garchFit(~arma(3,0)+garch(1,1), analyse)
I'm saving the results via

How to best divide table by table
Hi all,
how can I divide two tables of the same dimension so that all names are
preserved, ie do not become NA? I have "tab1" and "tab2", each having
names in the first column. I want "tab3" with the same names and values
"tab1/tab2".
Thanks,
Serguei

False alarm. For some reason that I have not yet been able to figure out, these tests run significantly more slowly when I run them during the daytime, which I did for that run. I checked a few of the worst regressions reported here and they all recovered in subsequent

[LLVMdev] 2.2 Prerelease available for testing
LLVMers,
The 2.2 prerelease is now available for testing:
http://llvm.org/prereleases/2.2/
If anyone can help test this release, I ask that you do the following:
1) Build llvm and llvm-gcc (or use a binary). You may build release
(default) or debug. You may pick llvm-gcc-4.0, llvm-gcc-4.2, or both.
2) Run 'make check'.
3) In llvm-test, run 'make TEST=nightly report'.

LLVMers,
The 2.1 pre-release (version 1) is available for testing:
http://llvm.org/prereleases/2.1/version1/
I'm looking for members of the LLVM community to test the 2.1
release. There are 2 ways you can help:
1) Download llvm-2.1, llvm-test-2.1, and the appropriate llvm-gcc4.0
binary. Run "make check" and the full llvm-test suite (make
TEST=nightly report).
2) Download

arma: what is the meaning of Pr(>|t|)?
In the summary of the output of arma, there's a number Pr(>|t|), however, I
don't know what is its meaning - at least, it doesn't _seem_ to be a
Student's t distribution.
Reproducible test case:
x <- c(0.5, sin(1:9))
reg <- arma(x, c(1,0))
summary(reg)
<output>
Call:
arma(x = x, order = c(1, 0))
Model:
ARMA(1,0)

4^2 factorial help
To whom it may concern:
I am trying a factorial design a system of mine that has two factors.
Each factor was set at four different levels, with one replication for
each of the combinations. My data is as follows:

No subject
I performed an aov() analysis and got the following results:
Df Sum Sq Mean Sq F value Pr(>F)
block 1 0.0040 0.0040 0.3282 0.5672
Residuals 269 3.2766 0.0122
Can anyone tell me how to extract the F value column and Pr(>F) column
from the summary output of aov analysis?
