taxTable2Taxid converts a table of taxonomic names to a table of
taxids. The format must be the same as curatedMetagenomicData (rowData) and
phyloseq (taxa_data).
taxTable2taxid(df, names_from)A data frame.
Name of the column with the names that should be used as rownames.
A data frame with taxIDs instead of names.
This function should always be run in an interactive session because it will ask for clarification when two taxonomic names belong to two different taxids.
