total_sum_abundance(data, ztransform = TRUE)

Arguments

data

matrix, the 'omics data matrix. Samples in rows, features 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 sum abundance and (2) total sum abundance at complete features for each samples.
