count_words {ds4psy}

Count the frequency of words in a string of text x.

Description

count_words provides frequency counts of the words in a string of text x as a named numeric vector.

Usage

count_words(x, case_sense = TRUE, sort_freq = TRUE)

Arguments

x

A string of text (required).

case_sense

Boolean: Distinguish lower- vs. uppercase characters? Default: case_sense = TRUE.

sort_freq

Boolean: Sort output by word frequency? Default: sort_freq = TRUE.

Details

Special (or non-word) characters are removed and not counted.

The quantification is case-sensitive and the resulting vector is sorted by name (alphabetically) or by frequency (per default).

Value

A named numeric vector.

# Options: 
count_words(s3, case_sense = FALSE)  # case insensitive
count_words(s3, sort_freq = FALSE)   # sorts alphabetically
