Usage

"sumTechReps"(x, ID=colnames(x), ...)
"sumTechReps"(x, ID=colnames(x), ...)

Arguments

x

a numeric matrix or DGEList object.

ID

sample identifier.

...

other arguments are not currently used.

Value

A data object of the same class as x with a column for each unique value of ID. Columns are in the same order as the ID values first occur in the ID vector.

Details

A new matrix or DGEList object is computed in which the counts for technical replicate samples are replaced by their sums.

x <- matrix(rpois(8*3,lambda=5),8,3)
colnames(x) <- c("a","a","b")
