Hi Joris,
sorry for the late response. But I was away for a couple of days. Apparently
i also did something wrong than.
Now both these loops are working as they suppose to.
Thanks again for all the help.

Hi Joris,
I guess i did it wrong again.
but your example didn't work either. I still get the error massage.

Hello R users,
I'm trying to extract random samples from a big array I have.
I have a data frame of over 40k lines and would like to produce around 50
random sample of around 200 lines each from this array.
this is the matrix
ID xxx_1c xxx__2c xxx__3c xxx__4c xxx__5T xxx__6T xxx__7T
Don't know what exactly you're trying to do, but you make a matrix
with 11 columns and 50 rows, then treat it as a vector. On top of
