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 knn to imput these missing values. I am doing tthis using 
knn.impute. Do I need to specify the various groups or can I just use the 
knn.impute command on the whole dataset together.

Also I am setting the maxp argument to the total number of values for each 
sample. Is this the correct thing to do?

Thanks in advance
