Dear John,

Have you read any documentation?  The meaning of the components returned 
by lmFit() are described briefly on the help page


and more mathematically on Section 10.2 "Fitted model objects" in the 
limma User's Guide.

Best wishes

I am not able to understand what R is doing in the background while
calculating the $stdev.unscaled and $sigma values from using the lmfit()
function for microarrays.

Any ideas?

Thanks in advance,

John Holden
