[R] coda sweave

[Ista Zahn]

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
