Create a vector of your REBL items from a data frame using a regex matching pattern.

Usage

id_rebl_items(df, pattern, ...)

Arguments

df

A data frame containing all the REBL items

pattern

A regex matching pattern

...

Additional arguments passed to grepl()

Value

A character vector of the names of your REBL items.

Details

This is a convenience function, but not essential in the workflow. If you already have a vector of your REBL item names, that works just as well. Using this function might be easier or harder depending on how items are named. If they are something like rebl_* this would work quite well. Otherwise, like in the example, we might have to use some "OR" operators to represent them all.

A vector of your REBL items will be required later in the workflow, however you choose to get it.
