regroup_taxa: Regroup some categories along a taxonomy
In jiho/zooprocessr: Read and analyse data generated by zooprocess

Description Usage Arguments Examples

Categories are usually labelled something like "crust_copepods_calanus", "crust_copepods_euchaeta", "crust_larvae", etc.; with different taxonomic levels separated by "_". This function regroups categories in higher level taxonomic units (such as "crust" here).

1	regroup_taxa(x, level = 1, pattern = NULL, separator = "_")

`x`	vector of categories (usually the "Valid" column of the data.frame produced by `read_ids`)
`level`	level at which to regroup (1 is what precedes the first separator, 2 is what precedes the second separator, etc.)
`pattern`	when provided, only act on categories whose name matches the pattern (matching is done by `stringr::str_detect`)
`separator`	character used to separate taxonomic levels in category names; usually "_"

x <- c("append_fritill", "append_housing", "crust_copepods_calanus", "crust_copepods_euchaeta", "crust_larvae")
regroup_taxa(x)
regroup_taxa(x, level=2)
regroup_taxa(x, pattern="crust")
