select significant features — select_sign

The output of this function can be passed in the features argument of the h_map function

select_sign_features(
  mRList = NULL,
  test_method = "anova",
  test_value = "q",
  cutoff_value = Inf,
  feature_id = "Feature_ID",
  values = FALSE,
  split_by_semicolon = FALSE
)

Arguments

mRList: mRList object
test_method: the name of the statistical test table contained in the mRlist object
test_value: the column of the statistical test table to consider (e.g.: p or q)
cutoff_value: the value of p-value cut-off to consider a feature as significant
feature_id: "Feature_ID", "Name" or "PubChemCID"; "Name" or "PubChemCID" require metabolite annotation
values: if TRUE a named vector with test_value values will be given in output; the beast value will be considered in case of 1-to-n mappings
split_by_semicolon: if TRUE, the names will be split by semicolons.

Value

a character vector with features names
