This function normalizes raw read counts to Reads Per Million (RPM) across each column (typically samples).
It is commonly used for comparing sequencing depth-normalized gene expression across samples.
Usage
readsPerMillion(data, factor = 10^6)
Arguments
- data
A numeric matrix or data frame of raw counts. Rows are typically genes, and columns are samples.
- factor
A numeric value for scaling. Default is 10^6 to compute reads per million.
Value
A matrix of the same dimensions as data, with RPM-normalized values.
