Yes Michael, it works well and I got the result what I want but it totally
depends on how reliable result do I want. When I take very high rho (near
about 1) and very low psi, it takes very long time may be it gives us more
accurate result. But for lower rho and higher psi, it gives immediately,

Thank you, i didn't know that the !operator is
also working for is.numeric etc.
Anyway I want to test if an argument is set in the
function call and if not a code is executed... So
far I tried:
f <-function(a,b){
if(!exists("b")) print("exists: b is not set")
if(is.null("b")) pri

Is there some reason you can't create the entire file in R and then write it
out in a single step?
It looks like you're writing out
mat[1, 1:10]
so you could just use
write.table(mat[1, 1:10], filen)
Can you expand on what you're trying to do?

Hi there,
I attach an excel file which I use to produce the data.
It simulates a simple AR(1) process y_t=0.5y_{t-1}+z_t.
In column E I have cut and paste values so that we can compare like with

When I run the ac
I have currently a R function that reads a csv file, does some computations,
produces some plots and writes a csv file as output. I would like to use
HTML forms to make a user interface for calling appropriate parts of the
functions (reading csv file, doing computations, displaying plots and

Hi, I am a quite beginner of random effect modelling.
Sorry for my ignorant question.
My question is about the values of lme function.
It returns coefficients which is a list with two components.
The R-help file says that it returns the estimated random effects for each
level of grouping.

I would like to write some data to different files. I can create the
filename Day1.txt like this:
filen <- paste("Day", l, ".txt", sep="")
and then I'm using a For loop to write out one row of a matrix,
something like this:
For (j in 1:10)
{
cat(mat[1,j], ",", file=filen, append=TRUE)
}
