meta.to.remove = c())

Arguments

dataset

list representing the dataset from a metabolomics experiment.

indexes

index vector with the samples that are going to be aggregated (e.g. c(1,1,2,2), this index vector will aggregate the first two samples and the last two samples).

aggreg.fn

aggregation function (e.g. "mean", "median", etc).

meta.to.remove

  ## Example of aggregating samples
  data(cassavaPPD)
  index.vector = c(1,1,2,2,2,2,2,1,1,3,3,3,3,3,1,4,4,4,4,4,5,5,6,6,6,6,6,5,5,
		  7,7,7,7,7,8,8,8,8,8,9,9,10,10,10,10,10,9,9,11,11,11,11,11,
		  9,12,12,12,12,12,13,13,14,14,14,14,14,13,13,15,15,15,15,15,
		  13,16,16,16,16,16)
  dataset = aggregate_samples(cassavaPPD, index.vector, "mean")
