Now i want to do some work with queue.I want to use single queue to
managing this.

problems with write.table, involving loops & paste statement
Hi!
I want to write portions of my data (3573 columns at a time) to twenty
folders I have available titled "A_1" to "A_20" such that the first 3573
columns will go to folder A_1, next 3573 to folder A_2 and so on.
This code below ensures that the data is written into all 20 folders, but
only the last iteration of the loop (last 3573 columns) is being written
into ALL of the

Numerical question
Hi all,
I have n independent variables A_1, A_2, A_3,......,A_n, and each with known variances var(A_1), var(A_2),..., but unknown mean. How can I get the approximation of the variance of the product of the variables using numerical computation, i.e. var(A_1*A_2*A_3*.....*A_n)? Thanks.

How to replace the values in a column
Dear All,
I've been searching relevant topics about replacing values, none seemed to
be applicable to me...
I have a file with many many varieties, and want to replace some of them
into different names.
I tried various of ways, still don't know how to do that most efficiently..
Here is part of the example data:
Gen Rep
A_1 1
A_1 2
A_2 1
A_2 2
B_1 1

Tail area of sum of Chi-square variables
Dear R experts,
I was wondering if there are any R functions that give the tail area
of a sum of chisquare distributions of the type:
a_1 X_1 + a_2 X_2
where a_1 and a_2 are constants and X_1 and X_2 are independent chi-square variables with different degrees of freedom.
Thanks,
Klaus

piece wise functions
Hello,
Apologies if this question has already arised, hope you can
help me to the find the solution to this or point the place to look at.
I have a multidimensional piece-wise regression linear problem, i.e.
to find not only the regression coefficients for each "interval" but
also the beginning and ends of the intervals.
To simplify it to the one dimensional case and
two intervals,

Please help with loop, thanks
Dear R helpers,
I would like to write a loop that makes 4 objects (called A, B, C, and D)
each of which contains ten random numbers.
This attempt:
individuals<-c("A","B","C","D")
for(i in 1:length(individuals)) {
individuals[i]<-rnorm(10)
}
does not work because "individuals[i]" is not the proper way to extract each

Package 'operators'
Folks,
In brief -- how many of you have found the 'operators' package to be
valuable in their work?
Not that I lack respect for the amount of work involved in creating and
maintaining a package, but I am unsure about the utility of these new
operators. Several of the operators appear to offer different ways of
accomplishing tasks that are already relatively easy in base R -- regular

multiple dimensional diag()
Hi
I have two arbitrarily dimensioned arrays, "a" and "b", with
length(dim(a))==length(dim(b)). I want to form a sort of
"corner-to-corner" version of abind(), or a multidimensional version
of blockdiag().
In the case of matrices, the function is easy to write and if
a=matrix(1,3,4) and b=matrix(2,2,2), then adiag(a,b) would return:
[,1] [,2] [,3] [,4] [,5]

Generate Simulation
Hallo everybody,
I'm new in r and I"ll appreciate some help!
I have a matrix of nrow=30 and ncoll=54,and I would like to generate 50
simulations with tha same size of the matrix!!!That is to say that I want
to generate 50 matrices -for my 50 simulations - with the same dimensions!
I took my 1st matrix according to the formula that I want to implement:

surf.ls
Hello,
I am looking into description of surf.ls(spatial)
and see under value $beta - the coefficients.
When I use polynomial of degree 2 to fit surface
I expect to get 4 coefficients:
z = a_1 x^2 + a_2 xy + a_3 y^2 + a_4
What do beta really stand for and why do I get
$beta vector of length 6?

how to use quadrature to integrate some complicated functions
Hello to all,
I am having trouble with intregrating a complicated uni-dimensional function
of the following form
Phi(x-a_1)*Phi(x-a_2)*...*Phi(x-a_{n-1})*phi(x-a_n).
Here n is about 5000, Phi is the cumulative distribution function of
standard normal,
phi is the density function of standard normal, and x ranges over
(-infty,infty).
My idea is to to use quadrature to handle this integral. But

Italicized greek symbols in PDF plots
I know that this has been asked before in other variations but I just can't
seem to figure out my particular application from previous posts. My
apologies if I have missed the answer to this question somewhere in the
archives. I have indeed looked.
I am running Ubuntu 11.04, with R 2.12.1 and ESS+Emacs.
For journal formatting requirements, I need to italicize all the greek

loops in R help me please
I am trying to make the following Kalman filter equations work and therefore produce their graphs.
v_t=y_t - a_t
a_t+1=a_t+K_t*v_t
F_t=P_t+sigma.squared.epsilon
P_t+1=P_t*(1-K_t)+sigma.squared.eta
K_t=P_t/F_t
Given:
a_1=0,P_1=10^7,sigma.squared.epsilon=15099,
sigma.squared.eta=1469.1
I have attached my code,which of course doesnt work.It produces NAs for the Fs,Ks and the a.
Can somebody tell me

fitting a curve according to a custom loss function
Dear R-Users,
I need to find a smooth function f() and coefficients a_i that give the best
fit to
y ~ a_0 + a_1*f(x_1) + a_2*f(x_2)
Note that it is the same non-linear transformation f() that is applied to
both x_1 and x_2.
So my first question is how can I do it in R?
A more general question is this: suppose I have a utility function U(a_i,
f()), where f() is say a spline. Is there a general

Constrain coefs. in linear model to sum to 0
Hello!
I would like to use constrain to sum coeficients of a factor to 0 instead
of classical corner contraint i.e. I would like to fit a model like
lm(y ~ 1 + effectA + effectB)
and say get parameters
intercept
effectA_1
effectA_2
effectB_1
effectB_2
effectB_3
where effectA_1 represents deviation of level A_1 from intercept and
sum(effectA_1, effectA_2) = 0 and the same for factor B.

Working with combinations
I am working with the combinations function (available in the gtools package). However, rather than store all of the possible combinations I would like to check each combination to see if it meets a certain criteria. If it does, I will then store it.
I have looked at the combinations code but am unsure where in the algorithm I would be able to operate on each combination.
Thanks!

character set for Windows?
I'm using cygwin to backup files from a windows machine to a unix host
with rsync. I originally uploaded the bulk of the files using a
windows ftp client, and then planned on doing updates nightly with
rsync.
Some of the filenames have strange characters in them, such as the
trademark symbol, and other characters, such as European letters.
Rsync doesn't like the filenames as they exist on

add trend line to each group of data in: xyplot(y1+y2 ~ x | grp...
Although this should be trivial, I'm having a spot of trouble.
I want to make a lattice plot of the format y1+y2 ~ x | grp but then fit a
lm to each y variable and add an abline of those models in different colors.
If the xyplot followed y~x|grp I would write a panel function as below, but
I'm unsure of how to do that with y1 and y2 without reshaping the data
before hand. Thoughts

Storing results in a single file after looping over all files
Hi All,
I have a whole lot of *.raw files in my working folder and I am doing the same analysis on each of those and want to save all the results in a single file. I am making some mistake here and can't figure out how to solve it.
Say, the *.raw files are ABCD.raw, EFGH.raw, IJKL.raw ...
The files are of this format
ID PHI?? aa1? aa2? aa3 ....
1??? 1???? 1.3?? 2.0?? 1.0
2??? 0????
