)

Arguments

sample.list	A named list of peak tables, one per sample.
metadata	Optional sample metadata.
description	Character string with a dataset description.
type	Character string describing the dataset type.

Value

A dataset object created from the input peak lists.

Examples

sample.list <- list(
  s1 = data.frame(ppm = c(1.0, 2.0), int = c(10, 20)),
  s2 = data.frame(ppm = c(1.0, 3.0), int = c(15, 30))
)
