I have a dataset from biological data with forty samples whichh relate to four 
different treatments. Each sample has thousands of values but as usuual contains 

missing values

I want to use EM to imput these missing values. I am doing tthis using 
amelia. Do I need to specify the various groups or can I just use the 
amelia command on the whole dataset (zz) together.

zzAmelia <- amelia(zz[,-1], m=5)

Also im not sure which value of m should be used

Thanks in advance
