Hi Yemi,

You have a common reference design. Have you read through the limma 
vignette? Try:

 >limmaUsersGuide()

See section 7.3 Common Reference Designs on how to create a design 
matrix where each treatment A-D is represented by a column. From 
there, you can go into section 8.8 Time Course Experiments to see how 
to create a contrast matrix to compare specific time points and/or 
use topTableF() to find genes that change over any time point.

HTH,
Jenny
