New Sampling question
I have another question about drawing samples from a data frame. This might
sound really tricky. Let me use a data frame I have posted earlier as an
example:
SubID CSE1 CSE2 CSE3 CSE4 WSE1 WSE2 WSE3 WSE4
1 6 5 6 2 6 2 2 4
2 6 4 7 2 6 6 2 3
3 5 5 5 5 5 5 4 5
4 5 4 3 4 4 4 5 2...
