[R] Simulation in R

Hello!

I have the following problem.

My code:

--snip--

ergebnisse <- rep(0, each=2)
stichproben <- rep(0, each=2)

for (i in seq(1:2)) {
n <- dim(daten)[1]
ix <- sample(n,200) # producing samples
samp_i <- daten[ix,]
stichproben[i] <- samp_i # doesn’t works

# Calculation of the model:
posterior_i <- MCMClogit(y ~ fbl.ind + fekq3 + febitda4 + fuvs + fkru + fzd + fur3, data=samp_i, b0=prior, B0=precision, tune=0.5) # calculation ergebnisse[i] <- summary(posterior_i) # saving the results (works) }

--snip--

I have a data set called "daten". I produce samples of the size 200. The samples are saved in samp_i.

Question:
How is the easiest way to save this samples. My code doesn't work, only the first column of the sample samp_i is in stichproben[i]. I understand why.
My idea is to define a array stichproben and then save a matrix in the
particular fields of the array. But things like y <- matrix(c(samp_1),nrow=200, ncol=8)
and then saving y in the array stichproben doesn't work. How is it possible to define a matrix with the content of my samples (samp_i) and but them into an array stichproben? Or is there an easier way?

With kind regards
Alex
