Needs sections to cover the following topics;
- Interaction of correlation, ndups, block arguements in analysis
- If 'block' is not 'NULL' then different arrays are assumed to be correlated.
- If 'block' is 'NULL' and 'ndups' is greater than one then replicate spots on the same array are assumed to be correlated.\
- It is not possible at this time to fit models with both a block structure and a duplicate-spot correlation structure simultaneously.
- If the argument 'block' is used, then it is assumed that 'ndups=1'.
- Improvement of details based on ?lmFit information
- Improve firstPrinciples.R article
