Hello Bioc members,

    I got a question about using limma to extract up-regulated genes 
from Affymetrix microarray datasets. 

I have created a design matrix, called lmfit, make the contrasts, call 
eBayes. But now I am stuck on what to do next. I check out the topTable 
function, but it only allows me to select differentially expressed 
genes. I am only interested in the up-regulated genes. How would I go 
about extracting only the up-regulated gnes?

 

Thank you!

Sincerely,

Victoria
