Hi R users,
I need to write a function that considers the row and column
autoregressive residual correlation structures. Usually
R=sigma^2_e*Identity matrix of order n, where n is the number of
observations and sigma^2_e is the usual residual error. I have to
consider an AR1 * AR1 where *
model that has both fixed and
several random effects. Which R packages or functions will help me to
accomplish this?
Thanks.
Laz

Thanks Jim,
What you have done is very good.
I was wondering if we could draw some horizontal and vertical lines to
separate the blocks. Is it possible using R?

Is Yoda an R package? I tried:
install.packages(Yoda)
Warning in install.packages :
package 'Yoda' is not available (for R version 3.0.1)

Hi,
fortune(Yoda) returns a quote of fortunes.
My problem was to draw horizontal and vertical lines to separate the
blocks in my design. Each block has 4 elements. The first and second
rows and columns are in block 1, 3rd and 4th rows and 1st and 2nd
columns are in 3 etc

Dear R users,
I have written a couple of R functions, some are through the help of the
R group members. However, running them takes days instead of minutes or
a few hours. I am wondering whether there is a quick way of doing that.
Here are all my R functions. The last one calls almost all of
to make it faster.
I used system.time()

I created a function which returns a value every time it's run (A
