removeBatchEffect
removeBatchEffect is a function in the limma package (Bioconductor) used to remove known batch effects from high-throughput expression data. It helps reduce non-biological variation introduced by differences between processing batches, enabling more accurate comparisons across samples.
The function operates by fitting a linear model to the expression data for each feature (such as
Typical usage involves pre-normalized or log-transformed data. The function is suited for microarray or other array-based
