fitting Markov chains
I need to find a computationally simple process for the movement of
interest rates. In this simplified model, an interest rate can have
3--5 possible values, and its movement is characterized by a matrix of
transition probabilities (ie, it is a Markov process).
I would like to estimate this process from a given set of data.
For example, let the interest rate time series be:

A matrix automation problem
[I am really sorry if it is double posted, I doubt me previous post could not
reach forum due to some problem with net]
Suppose I have a matrix :
a = matrix(1:9, 3)
>From this matrix, I construct 9 additional matrices :
i = 1:9
bi = a * i
Now combining all those 9 new matrices, I construct a final metrix as :
c =
b1 b4 b7
b2 b5 b8
b3 b6 b8
I want to automate this procedure for any

vlmc - "In vlmc(traffic.clusters.stationary, cutoff = i) : alphabet with >1-letter strings; trying to abbreviate"
Dear all (copying the package author),
I have a question on the vlmc package. I am trying to model a time series, where each element can take one of 11 values (the result of some clustering). When I run the following command (synthetic data to facilitate self-contained example) I get the following warning: ("alphabet with >1-letter strings; trying to abbreviate")

Fwd: Re: How to create following chart for visualizing multivariate time series
Thanks David, It is working. Holtman's also gave me a solution but, I wanted to have a color pallet for description of colors, that was not in his solution.
However I need one small modification. If I want to plot only lower diagonal elements of 'dat' then how should I proceed? What I want is, to visualize only lower diagonal elements and having the color pallet on them only. Also

How to create following chart for visualizing multivariate time series
Let me take an artifical matrix :
dat = matrix(rnorm(200*200), 200, 200)
My goal is to visualize this matrix according to the procedure, described in previous mails. I took Mendelssohn's advice and got following advice :
?plot.im
Z <- setcov(owin())
plot(Z) .................... etc
However I can not reproduce this example in my problem. How I can change my data

Extracting part of date variable
Dear all,
Suppose I have a date variable:
c = "99/05/12"
I want to extract the parts of this date like month number, year and day. I can do it in SPSS. Is it possible to do this in R as well?

Random sample from log-normal distribution
Dear all R users,
Please forgive me if my question is too trivial.
Suppose I have two variables, (x,y) which is
log-normally distributed with expected value (mu1,
mu2) and some variance-covariance matrix. Now I want
to draw a random sample of size 1000 from this
distribution. Is there any function available to do
this?
Thanks and regards,

Panel data
Dear all R users,
I have a small doubt about panel data analysis. My basic understanding on Panel data is a type of data that is collected over time and subjects. Vector Autoregressive Model (VAR) model used on this type of data. Therefore can I say that, one of statistical tools used for analysis of panel data is VAR model? If you clarify my doubt I will be very grateful.
Thanks and regards,

Fwd: Re: How to create following chart for visualizing multivariate time series
I used ?image function to do that, like below :
require(grDevices) # for colours
x <- y <- seq(-4*pi, 4*pi, len=27)
r <- sqrt(outer(x^2, y^2, "+"))
image(x, y, r, col=gray((0:32)/32))
However my next problem to add a color pallet for color description [as shown in following link]. If anyone here tell me how to do that, it will be good for me.

I am struggling to understand the johansen test procedure in the context of co-integration in time series. Yes I understand that this forum is not directly statistics related but still I am posting here hoping that I would get som help.

Putting column names in some automated way

I have following codes:

Now I want construct a "for" loop starting from 1 to 3 to give the new names of columns for dataframe "data" like below

Definitely I could do this manually, however I want to put
