read.transcript: Read Transcripts Into R

In trinker/qdap2: Bridging the gap between qualitative data and quantitative analysis

Description

Read .docx, .csv or .xlsx files into R.

Usage

  read.transcript(file, col.names = NULL, text.var = NULL,
    merge.broke.tot = TRUE, header = FALSE, dash = "",
    ellipsis = "...", quote2bracket = FALSE,
    rm.empty.rows = TRUE,
    na.strings = c("999", "NA", "", " "), sep = NULL,
    skip = 0, nontext2factor = TRUE, ...)

Arguments

file	The name of the file which the data are to be read from. Each row of the table appears as one line of the file. If it does not contain an absolute path, the file name is relative to the current working directory, getwd().
col.names	A character vector specifying the column names of the transcript columns.
text.var	A character string specifying the name of the text variable will ensure that variable is classed as character. If NULL read.transcript attempts to guess the text.variable (dialogue).
merge.broke.tot	logical. If TRUE and if the file being read in is .docx with broken space between a single turn of talk read.transcript will attempt to merge these into a single turn of talk.
header	logical. If TRUE the file contains the names of the variables as its first line.
dash	A character string to replace the en and em dashes special characters (default is to remove).
ellipsis	A character string to replace the ellipsis special characters (default is text ...).
quote2bracket	logical. If TRUE replaces curly quotes with curly braces (default is FALSE). If FALSE curly quotes are removed.
rm.empty.rows	logical. If TURE read.transcript attempts to remove empty rows.
na.strings	A vector of character strings which are to be interpreted as NA values.
sep	The field separator character. Values on each line of the file are separated by this character. The default of NULL instructs read.transcript to use a separator suitable for the file type being read in.
skip	Integer; the number of lines of the data file to skip before beginning to read data.
nontext2factor	logical. If TRUE attempts to convert any non text to a factor.
...	Further arguments to be passed to read.table.

Value

Returns a dataframe of dialogue and people.

Warning

read.transcript may contain errors if the file being read in is .docx. The researcher should carefully investigate each transcript for errors before further parsing the data.

Note

If a transcript is a .docx file read transcript expects two columns (generally person and dialogue) with some sort of separator (default is colon separator). .doc files must be converted to .docx before reading in.

dat1 <- read.transcript(doc1)
truncdf(dat1, 40)
dat2 <- read.transcript(doc1, col.names = c("person", "dialogue"))
truncdf(dat2, 40)
dat2b <- rm_row(dat2, "person", "[C") #remove bracket row
truncdf(dat2b, 40)

## read.transcript(doc2) #throws an error (need skip)
dat3 <- read.transcript(doc2, skip = 1); truncdf(dat3, 40)

## read.transcript(doc3, skip = 1) #throws an error; wrong sep
dat4 <- read.transcript(doc3, sep = "-", skip = 1); truncdf(dat4, 40)

dat5 <- read.transcript(doc4); truncdf(dat5, 40) #an .xlsx file
