Normalization data by the median value of each batch
Usage
batch_norm(
object,
feature_platform = "PLATFORM",
QC_ID_pattern = "MTRX",
test = FALSE,
verbose = TRUE
)Arguments
- object
A Metabolite object. In the feature annotation slot `feature`, a platform column should be provided for metabolite measurement platform (eg. `PLATFORM`). The values in the `PLATFORM` column (eg. `Neg`, `Polar`, `Pos Early`, and `Pos Late`) are column names in the sample annotation `sample` to determine the batches of samples.
- feature_platform
The column name of feature platform for metabolite measurements (eg. `PLATFORM`).
- QC_ID_pattern
A character pattern to determine QC samples. Default value: "MTRX".
- test
test the function for the first 20 columns.
- verbose
print log information.
