there, and then to shut down the win2000 Server and to Activate the
CentOS as domain controller?

a really simple question on polynomial multiplication
Dear R people:
Is there a way to perform simple polynomial multiplication; that is,
something like
(x - 3) * (x + 3) = x^2 - 9, please?
I looked in poly and polyroot and expression. There used to be a
package that had this, maybe?
thanks,
Erin

Fw: Problem to create a matrix polynomial
Awaiting some suggestion. Was my question not very understandable? Please let me know how can I offer more elaborate clarification.
Additionally, I would like to solve the determinant of "p1" for the values of "z" (I am working with some multivariate time series modelling). When I use det() function, it am getting error that, that function is not for objects with class

How to get solution of following polynomial?
Hi, I want find all roots for the following polynomial :
a <- c(-0.07, 0.17); b <- c(1, -4); cc <- matrix(c(0.24, 0.00, -0.08,
-0.31), 2); d <- matrix(c(0, 0, -0.13, -0.37), 2); e <- matrix(c(0.2, 0,
-0.06, -0.34), 2)
A1 <- diag(2) + a %*% t(b) + cc; A2 <- -cc + d; A3 <- -d + e; A4 <- -e
fn <- function(z)
{
y <- diag(2) - A1*z - A2*z^2 - A3*z^3 - A4*z^4

DierckxSpline segfault
I've just encountered a segfault when using DierckxSpline::percur
function. Below is the minimal example which triggers the error:

x <- 1:10
y <- rep(0, 10)
pspline <- percur(x, y)

functions for polynomial and rational interplation?
Are there implementations of, e.g. Neville's algorithm, for interpolating
polynomials through some data points? Nevilles' is an improvement on
Lagrange interpolation. And how about interpolating rational functions? I
could not find anything at rseek.org or at crantastic.org.
thanks

Cambiar el formato de datos
Estimados miembros de la comunidad de R
Tengo el siguiente formato en un fichero csv que corresponde a datos de la
población para un conjunto de países y para un rango amplio de años.
Pais 1960 1961 1962 1963
Albania vvvvv vvvv
Algeria vvvvv vvvv
Me gustaría pasarlo a la siguiente forma

Cambiar el formato de datos
Después del "gather()" puedes hacer un "arrange()" que es una ordenación. Y
dentro de "arrange()" le indicas la variable por la que ordenas (no hacen
falta comillas)...
Lo ordenará alfabéticamente.

Merging rows in a dataframe
Hi R Help list
I'm looking to visualise US foreign aid 1946-2009 and I have the dataset for this. The trouble is it's a bit too complex and I need to simply it
I want to merge all of the rows with the same country together and add up the individual totals to make one total figure per country per year
Below is an example of the kind of data. The real dataset has 2447 rows and covers 63

[R] Increasing number of observations worsen the regression model
Yes, it is important that it only happens with certan BLAS, so probably not really an R issue.
However, there has been some concern over the C/Fortran interfaces lately, so if you could narrow it down to a specific BLAS routine, it could prove useful for the developers.
One fairly easy thing to do would be to find the breakdown point. I speculate that it could be at 16384 (=2^14) and that some

gauss.hermite?
The search at www.r-project.org mentioned a function
"gauss.hermite{rmutil}". However, 'install.packages("rmutil")'
produced, 'No package "rmutil" on CRAN.' How can I find the current

Running a column loop through the Moran.I function.
Dear R users,
I have two data frames that consist of statistical information for most
countries around the world. One dataframe consists of the latitude and
longitude ("coord.csv") of each country, while the other consists of 100's
of different attributes ("countryattri.csv") for each country (like, GDP,
Population, etc.). The data is organized with a header and then

diff() for panel data
Hello, everyone!
I'd like to find out how I can do first log differences in a panel?
(The Penn World Table data that's available in the PWT package)
The regular diff() function ignores the country/index/"panel unit",
with depressing results.
A second request, how can I best "filter" the data (e.g. generate a
data frame with the data for a single country or a single

Why using hypercall_page ?
Hello,
I am studing Xen hypercall now. I found that hypercall is invoked via
hypercall_page, which is only filled with (in
no-hypervisor-kernel-mode ):
mov $i, %eax
int $0x82
ret
Why not invoked the hypercall directly by "int $0x82" ? What''s the
advantage of using hypercall_page?
Thanks,
Wu

R limits documented?
Is there documentation on R limits?
That is, max matrix size, etc.?
Diagnostics when limits are exceeded are not always
meaningful. For example:
> x <- rep(0,50000*50000)
Error in rep(0, 50000 * 50000) : invalid 'times' argument
In addition: Warning message:
In as.vector(data) : NAs introduced by coercion
