cm_df.temp: Break Transcript Dialogue into Blank Code Matrix

Description

Breaks transcript dialogue into words while retaining the demographic factors associate with each word. The codes argument provides a matrix of zeros that can serve as a dummy coded matrix of codes per word.

Usage

cm_df.temp(dataframe, text.var, codes = NULL, file = NULL,
  transpose = FALSE, strip = FALSE, ...)

Arguments

dataframe

A dataframe containing a text variable.

text.var

The name of the text variable.

codes

Optional list of codes.

file

The name of the file (csv is recommended file type). If NULL no file is written.

transpose

logical. If TRUE transposes the dataframe so that the text is across the top.

strip

logical. If TRUE all punctuation is removed.

...

Other arguments passed to strip.

Value

• Generates a dataframe, and optional csv file, of individual words while maintaining demographic information. If a vector of codes is provided the outcome is a matrix of words used by codes filled with zeros. This dataframe is useful for dummy coded (1-yes code exists; 0-no it does not) representation of data and can be used for visualizations and statistical analysis.
