WebedgeR stores data in a simple list-based data object called a DGEList. This type of object is easy to use because it can be manipulated like any list in R. You can make this in R by specifying the counts and the groups in the function DGEList(). d &lt;- DGEList(counts=mobData,group=factor(mobDataGroups)) d WebA list is not a matrix, so that's why it doesn't work. There are a number of issues with what you are doing. For starters, you should supply the raw counts to edgeR, not normalized values.You should be using normalization factors; you should be filtering; and you should be using the DGEList data structure to coordinate this across the analysis..
