Inserting data into a data frame based on the unique combination of two factors?

Let's suppose you have the file names in a vector datafiles such that files 1-4 are the data for all assays for samples 1-384, 5-8 for all assays for samples 385-768, and so on, and that you want to end up with a data frame that is 1536 rows by 162 columns.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
