unnest_term_list: Unnest a Nested Term List

In trinker/termco: Counts of Terms and Substrings

Description

Term lists can be stored as lists within a list for use in termc_count in a hierarchical fashion. This structure is not always useful and can be taken to a single nest via unnest_term_list. The function detects if the term.list is nested or not and then unnests only if needed, thus allowing it to be safely used on both nested and unnested term.lists.

Usage

unnest_term_list(term.list, ...)

Arguments

term.list

A list of named character vectors. 'codeterm_count can be used in a hierarchical fashion as well; that is a list of regexes can be passed and counted and then a second (or more) pass can be taken wit a new set of regexes on only those rows/text elements that were left untagged (count rowSums is zero). This is accomplished by passing a list of lists of regexes. See Examples for the hierarchical terms section for a demonstration.

...

ignored.

Value

Returns a list of one level.

Examples

x <- list(
    a = setNames(as.list(LETTERS[1:5]),LETTERS[1:5]),
    b = setNames(as.list(LETTERS[6:11]), LETTERS[6:11])
)
y <- list(a=LETTERS[1:11])
unnest_term_list(x)
unnest_term_list(y)
