Peter and Po Su, thanks.
For those who haven't read it, it attempts

* provide an overview of the world of R

* tell of ways to find objects and information

Thank you Martin for your advices.
Let me give more information about my matrices. I am working on a
space-time model, it is a very simple model based on second-moment
assumption. My model is
E(Y) = g(X%*%beta) - g is a suitable link function
V(Y) = C = V^{1/2} Omega V^{1/2} - It is my
Dear all,
I have a data frame, where multible process and ordering done ..can I re

example
Xi items numrber_list_items

27 7, 3, 40

Hello,
If your data.frame is named 'dat', try something like the following.
dat[order(rownames(dat)), ]
Hope this helps,

Hi,
You don't show us your code, and you really should, but most likely
you did not put the file where you thought you did, or there's a typo

Using file.choose() may help.
Also, I think it's bad practice to put user files in the R library

Such problems usually come from not understanding where files really are,
though sometimes odd file permissions can be the culprit. Understanding how
backslashes work in R strings also sometimes causes problems, though you seem
to be using forward slashes so that may not apply here.
You may

Hi,
I would like to deploy a R script such that it can be run as batch commando
on generic Window machines.
After reading a bit about deploy possibilities I see that the recommended
way is to include the whole R installation catalog and then run R from
command line from within that catalog.
For future reference, perhaps creating an index variable when the data
frame is first created and before ³multiple process and ordering² is done
would be good.
