cm_df.temp: Break Transcript Dialogue into Blank Code Matrix

In trinker/qdap: Bridging the Gap Between Qualitative Data and Quantitative Analysis

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.
