Test for differential expression for 3 groups
Now that you've specified the design matrix and the contrasts matrix, you can test for differential expression.
Diese Übung ist Teil des Kurses
Differential Expression Analysis with limma in R
Anleitung zur Übung
The ExpressionSet object eset with the hypoxia data, the design matrix (design), and the contrasts matrix (cm) have been loaded in your workspace.
Fit the model coefficients with
lmFit.Fit the contrasts with
contrasts.fit.Calculate the t-statistics with
eBayes.Summarize the results with
decideTests.
