The lexical density is the proportion of content words (lexical items) in documents. This function is a simple helper for calculating the lexical density of given datasets.
Usage
lex_density(vec, contents_words, targets = NULL, negate = c(FALSE, FALSE))Arguments
- vec
A character vector.
- contents_words
A character vector containing values to be counted as contents words.
- targets
A character vector with which the denominator of lexical density is filtered before computing values.
- negate
A logical vector of which length is 2. If passed as
TRUE, then respectively negates the predicate functions for counting contents words or targets.
