taxa_rollup: Roll up data to a specified taxonomic level
In pmartR/pmartRseq: Analysis and Visualization of 16S Data

Description Usage Arguments Details Value Author(s) Examples

This function rolls up data to the specified taxonomic level so that statistics may be calculated at various taxonomic levels.

1	taxa_rollup(omicsData, level, taxa_levels = NULL)

`omicsData`	an object of the class 'seqData' created by `as.seqData`.
`level`	taxonomic level to roll up to.
`taxa_levels`	The levels of taxonomy (or other e_meta object) which might be used in the roll up. If NULL, will use c("Kingdom","Phylum","Class","Order","Family","Genus","Species"), in that order. Default is NULL.

Data will be rolled (summed) up to a specified taxonomic level. For example, data at the OTU level could be rolled (summed) up to the Genus level before statistics are computed.

A seqData object of the same class as the input, where e_data and e_meta are rolled up to the specified level.
