ExprData-class {MIGSA} | R Documentation |
This S4 class contains the expression data, it can be a MAList or DGEList. Important: Rownames are going to be used as gene identifiers, make sure that this IDs are the same used in your gene sets.
## Lets create a ExprData object from counts data (DGEList). rnaData <- matrix(rnbinom(10000,mu=5,size=2),ncol=4); rownames(rnaData) <- 1:nrow(rnaData); # It must have rownames (gene names). ## Now we can use rnaExprData as an ExprData object. ## Not run: rnaExprData <- DGEList(counts=rnaData); ## End(Not run) ## Lets create a ExprData object from micro array data (MAList). maData <- matrix(rnorm(10000),ncol=4); rownames(maData) <- 1:nrow(maData); # It must have rownames (gene names). ## Now we can use maExprData as an ExprData object. maExprData <- new("MAList",list(M=maData));
