Usage

markerScoreMaxcol(object)

A numeric matrix, an object of class ExpressionSet, or a MarkerList-class object.

Details

Genes are assigned to their respective maximum expressing column/value and returned as a MarkerList object.

Examples


# random data matrix with rownames (needed)
x <- rmatrix(20, 3)
rownames(x) <- paste("g", 1:nrow(x), sep='_')

# compute score
markerScoreMaxcol(x)
## <object of class: MarkerList>
## Types: 1, 2, 3 (total: 3)
## Mode: numeric
## setName: NA 
## geneIds: g_1, g_2, ..., g_19 (total: 20)
## geneIdType: Null
