This function estimates total peak abundance|area for numeric data in a matrix, for (1) all features and (2) all features with complete data.
Usage
total_peak_area(data, ztransform = TRUE)
Arguments
- data
matrix, the metabolite data matrix. Samples in rows, metabolites in columns
- ztransform
logical, should the feature data be z-transformed and absolute value minimum, mean shifted prior to summing the feature values. TRUE or FALSE.
Value
a data frame of estimates for (1) total peak abundance and (2) total peak abundance at complete features for each samples
