Differential Expression Analysis with limma in R
Petunjuk latihan
The ExpressionSet object eset with the leukemia data and the design matrix you just created (design) have been loaded in your workspace.
Fit the model coefficients with
lmFit.Calculate the t-statistics with
eBayes.Summarize the results with
decideTests.Since it doesn't make sense to test the intercept term, specify the coefficient
"Diseasestable"when runningdecideTests.
Latihan interaktif praktis
