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. |
A Metabolite object after normalization.
