In ds4psy: Data Science for Psychologists

Count the frequency of words in a string of text

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.

# Default:

        "A third --- and also THE FINAL --- SENTENCE.")
count_words(s3)  # case-sensitive, sorts by frequency 

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