Sum Over Replicate Samples
Condense the columns of a matrix or DGEList object so that counts are summed over technical replicate samples.
## Default S3 method: sumTechReps(x, ID=colnames(x), ...) ## S3 method for class 'DGEList' sumTechReps(x, ID=colnames(x), ...) ## S3 method for class 'SummarizedExperiment' sumTechReps(x, ID, ...)
x |
a numeric matrix or |
ID |
sample identifier. |
... |
other arguments are not currently used. |
A new matrix or DGEList object is computed in which the counts for technical replicate samples are replaced by their sums.
A data object of the same class as x with a column for each unique value of ID.
For a SummarizedExperiment object, it is converted into a DGEList object.
Columns are in the same order as the ID values first occur in the ID vector.
