Thank you so much Ista.
I have problems with pictures too.

Why doesn't this work ? Sorry for posting all these questions :-(
Best,
Randall
Check out FAQ 7.22. You need to use
print(xyplot(mcmc(x)))
since inside an Sweave evaluation, you are not at the command line and
it does not print by default.

Hi Randall,
Sounds like you need to make friends with the str() function, and
perhaps read the documentation about data types in R. For your
particular problem:
library(coda)
m1<- matrix(runif(100), nrow=10)
m1.sum<- summary(mcmc(m1))
str(m1.sum)
library(xtable)
xtable(m1.sum$statistics)
xtable(m1.sum$quantiles)
Best,
Ista

This is the kind of output I get with summary(mcmc(x)). I would like it
in
LaTeX. There are two tables.
Iterations = 1:10
Thinning interval = 1
Number of chains = 1
Sample size per chain = 10
1. Empirical mean and standard deviation for each variable,
plus standard error of the mean:
Mean SD Naive SE Time-series SE
[1,] 0.7237 3.374 1.067 1.252
[2,] -1.7883 4.317 1.365 1.644
[3,] 0.8384 3.422 1.082 1.047
[4,] 1.0750 3.195 1.010 1.087
2. Quantiles for each variable:
2.5% 25% 50% 75% 97.5%
var1 -1.5408 -0.91681 -0.1798 0.7134 7.929
var2 -4.1454 -3.89975 -3.5207 -2.1781 7.706
var3 -2.0412 -0.79606 0.3247 1.0445 7.999
var4 -0.9809 -0.08847 0.1895 0.4980 8.015
Thank you very much for any help,
Randall

I forgot to say that the coda package is loaded.

Dear R users,
I have a matrix x of simulated values. Each column corresponds to one
variable.
summary(mcmc(x)) works fine
I would like however to transform the ouput into a nice LaTeX code.
xtable( summary(mcmc(x)) ) does not work.
Thanks
Randall
