wordcounts_remove_rare R Documentation
Remove infrequent words
Description
Filter out the words in a wordcounts dataframe whose overall frequency is
below a threshold.
Usage
wordcounts_remove_rare(counts, n)
Arguments
counts
The dataframe from read_wordcounts
n
The maximum rank to keep: all words with frequency rank below
n will be discarded
Details
It's often useful to prune documents of one-off words (many of which are
OCR errors) before building MALLET instances. This is a convenience function
for doing so.
Value
A filtered word-counts dataframe. Because of ties, do not expect
it to have exactly n distinct words.
