ExprData-class {MIGSA} | R Documentation

## ExprData S4 class implementation in R

### Description

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.

### Examples

    ## 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));
