...8 columns and in about 5000 rows. What I want to do is to generate samples of this data set. Samples of a special size, as example 200. What is the easiest way to do this? No special things are needed, only the random selection of 200 rows of the data set.

...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?

...produce 50 samples in a first turn and then produce 50 samples again in another turn, but this can not be a "clean" solution (and surely not the only one). Hopefully you can help me and this is the last question for my simulation.
