text	to be analyzed; for vader_df(), the text should be a single vector (e.g. 1 column)
incl_nt	defaults to T, indicates whether you wish to incl UNUSUAL n't contractions (e.g., yesn't) in negation analysis
neu_set	defaults to T, indicates whether you wish to count neutral words in calculations
rm_qm	defaults to T, indicates whether you wish to clean quotation marks from text (setting to F may result in errors)

Value

A dataframe containing the valence score for each word; an overall, compound valence score for the text; the weighted percentage of positive, negative, and neutral words in the text; and the frequency of the word "but".
