Description

Takes the year value in the last two digits of the sample ID and allows selection of a single year of data. Can be performed on tables at higher taxonomic levels generated by combine_otus(), or on tables already subset by bog_subset().

Usage

Arguments

table

year_id

Two digit code indicating the last two digits of the year of interest (05, 07, 08, 09) surrounded by quotes. Regular expressions can be used.
