textreadr is a small collection of convenience tools for reading text documents into R. This is not meant to be an exhaustive collection; for more see the tm package.

Table of Contents

Functions

Most jobs in my workflow can be completed with read_document and read_dir. The former generically reads in a .docx, .doc, .pdf, .html, or .txt file without specifying the extension. The latter reads in multiple .docx, .doc, .rtf, .pdf, .html, or .txt files from a directory as a data.frame with a file and text column. This workflow is effective because most text documents I encounter are stored as a .docx, .doc, .rtf, .pdf, .html, or .txt file. The remaining common storage formats I encounter include .csv, .xlsx, XML, structured .html, and SQL. For these first 4 forms the readr, readxl, xml2, and rvest. For SQL:

R Package SQL
ROBDC Microsoft SQL Server
RMySQL MySQL
ROracle Oracle
RJDBC JDBC

These packages are already specialized to handle these very specific data formats. textreadr provides the basic reading tools that work with the five basic file formats in which text data is stored.

The main functions, task category, & descriptions are summarized in the table below:

Function Task Description
read_transcript reading Read 2 column transcripts
read_docx reading Read .docx
read_doc reading Read .doc
read_rtf reading Read .rtf
read_document reading Generic text reader for .doc, .docx, .rtf, .txt, .pdf
read_html reading Read .html
read_pdf reading Read .pdf
read_dir reading Read and format multiple .doc, .docx, .rtf, .txt, .pdf files
read_dir_transcript reading Read and format multiple transcript files

)

pdf_doc_img <- system.file("docs/McCune2002Choi2010.pdf", package = "textreadr")

Download & Browse

The download and browse functions are utilities for downloading and opening files and directories.

Download

download is simply a wrapper for curl::curl_download that allows multiple documents to be download, has the tempdir pre-set as the destfile (named loc in textreadr), and also returns the path to the file download for easy use in a magrittr chain.

Here I download a .docx file of presidential debated from 2012.

'https://github.com/trinker/textreadr/raw/master/inst/docs/pres.deb1.docx' %>%
    download() %>%
    read_docx() %>%
    head(3)

## pres.deb1.docx read into C:\Users\trinker\AppData\Local\Temp\RtmpgVzUqi

## [1] "LEHRER: We'll talk about -- specifically about health care in a moment. But what -- do you support the voucher system, Governor?"                           
## [2] "ROMNEY: What I support is no change for current retirees and near-retirees to Medicare. And the president supports taking $716 billion out of that program."
## [3] "LEHRER: And what about the vouchers?"

Browse

browse is a system dependent tool for opening files and directories. In the example below we open the directory that contains the example documents used in this README.

system.file("docs", package = "textreadr") %>%
    browse()

We can open files as well:

html_doc %>%
    browse()

Generic Document Reading

The read_document is a generic wrapper for read_docx, read_doc, read_html, and read_pdf that detects the file extension and chooses the correct reader. For most tasks that require reading a .docx, .doc, .html, .pdf, or .txt file this is the go-to function to get the job done. Below I demonstrate reading each of these five file formats with read_document.

docx_doc %>%
    read_document() %>%
    head(3)

## [1] "JRMC2202 Audio Project"      "Interview Transcript"       
## [3] "Interviewer: Yasmine Hassan"

doc_doc %>%
    read_document() %>%
    head(3)

## [1] "JRMC2202 Audio Project"      "Interview Transcript"       
## [3] "Interviewer: Yasmine Hassan"

rtf_doc %>%
    read_document() %>%
    head(3)

## [1] "Researcher 2:\tOctober 7, 1892."          
## [2] "Teacher 4:\tStudents it’s time to learn." 
## [3] "[Student discussion; unintelligible]"

pdf_doc %>%
    read_document() %>%
    head(3)

## [1] "Interview with Mary Waters Spaulding, August 8, 2013"                                          
## [2] "CRAIG BREADEN: My name is Craig Breaden. I’m the audiovisual archivist at Duke University,"    
## [3] "and I’m with Kirston Johnson, the curator of the Archive of Documentary Arts at Duke. The date"

Read Directory Contents

Often there is a need to read multiple files in from a single directory. The read_dir function wraps other textreadr functions and lapply to create a data frame with a document and text column (one row per document). We will read the following documents from the 'pos' directory in textreadr's system file:

levelName
pos          
  |--0_9.txt  
  |--1_7.txt  
  |--10_9.txt 
  |--11_9.txt 
  |--12_9.txt 
  |--13_7.txt 
  |--14_10.txt
  |--15_7.txt 
  |--16_7.txt 
  |--17_9.txt 
  |--18_7.txt 
  |--19_10.txt
  |--2_9.txt  
  |--3_10.txt 
  |--4_8.txt  
  |--5_10.txt 
  |--6_10.txt 
  |--7_7.txt  
  |--8_7.txt  
  \--9_7.txt

Here we have read the files in, one row per file.

system.file("docs/Maas2011/pos", package = "textreadr") %>%
    read_dir() %>%
    peek(Inf, 40)

Read .docx

A .docx file is nothing but a fancy container. It can be parsed via XML. The read_docx function allows the user to read in a .docx file as plain text. Elements are essentially the p tags (explicitly //w:p) in the markup.

docx_doc %>%
    read_docx() %>%
    head(3)

## [1] "JRMC2202 Audio Project"      "Interview Transcript"       
## [3] "Interviewer: Yasmine Hassan"

docx_doc %>%
    read_docx(15) %>%
    head(3)

## [1] "Hassan:           Could you please tell me your name, your title, your age, and your place of ref,                                   umm, residence?"
## [2] "Abd Rabou:   My name is Ahmad Abd Rabou. I’m assistant professor of comparative politics at"                                                         
## [3] "both Cairo University and The American University in Cairo. I’m 34 years old. I"

Read .doc

A .doc file is a bit trickier to read in than .docx but is made easy by the antiword package which wraps the Antiword program in an OS independent way.

doc_doc %>%
    read_doc() %>%
    head()

## [1] "JRMC2202 Audio Project"      "Interview Transcript"       
## [3] "Interviewer: Yasmine Hassan" "Narrator: Ahmad Abd Rabou"  
## [5] "Date: 16/10/2014"            "Place: Narrator's office"

doc_doc %>%
    read_doc(15) %>%
    head(7)

## [1] "Hassan:           Could you please tell me your name, your title, your age,"
## [2] "and your place of ref,"                                                     
## [3] "umm, residence?"                                                            
## [4] "Abd Rabou:   My name is Ahmad Abd Rabou. I'm assistant professor of"        
## [5] "comparative politics at"                                                    
## [6] "both Cairo University and The American University"                          
## [7] "in Cairo. I'm 34 years old. I"

Read .rtf

Rich text format (.rtf) is a plain text document with markup similar to latex. The striprtf package provides the backend for read_rtf.

rtf_doc %>%
    read_rtf() 

## [1] "Researcher 2:\tOctober 7, 1892."                                                                                                                                                                                                                                                                                                                              
## [2] "Teacher 4:\tStudents it’s time to learn."

Read .pdf

Like .docx a .pdf file is simply a container. Reading PDF's is made easier with a number of command line tools. A few methods of PDF reading have been incorporated into R. Here I wrap pdftools pdf_text to produce read_pdf, a function with sensible defaults that is designed to read PDFs into R for as many folks as possible right out of the box.

Here I read in a PDF with read_pdf. Notice the result is a data frame with meta data, including page numbers and element (row) ids.

pdf_doc %>%
    read_pdf() 

## Table: [616 x 3]
## 
##    page_id element_id text

Image Based pdf: OCR

Image based .pdfs require optical character recognition (OCR) in order for the images to be converted to text. The ocr argument of read_pdf allows the user to read in image based .pdf files and allow the tesseract package do the heavy lifting in the backend. You can look at the .pdf we'll be using by running:

browse(pdf_doc_img)

First let's try the task without using OCR.

pdf_doc_img %>%
    read_pdf(ocr = FALSE)

## Table: [0 x 3]
## 
## [1] page_id    element_id text      
## <0 rows> (or 0-length row.names)
## ... ...        ...        ...

And now using OCR via tesseract. Note that ocr = TRUE is the default behavior of read_pdf.

pdf_doc_img %>%
    read_pdf(ocr = TRUE)

## Converting page 1 to C:\Users\AppData\Local\Temp\RtmpKeJAnL/McCune2002Choi2010_01.png... done!

Read .html

Often a researcher only wishes to grab the text from the body of .html files. The read_html function does exactly this task. For finer control over .html scraping the user may investigate the xml2 & rvest packages for parsing .html and .xml files. Here I read in HTML with read_html.

html_doc %>%

Read Transcripts

Many researchers store their dialogue data (including interviews and observations) as a .docx or .xlsx file. Typically the data is a two column format with the person in the first column and the text in the second separated by some sort of separator (often a colon). The read_transcript wraps up many of these assumptions into a reader that will extract the data as a data frame with a person and text column. The skip argument is very important for correct parsing.

Here I read in and parse the different formats read_transcript handles. These are the files that will be read in:

basename(trans_docs)

docx With Skip

skip is important to capture the document structure. Here not skipping front end document matter throws an error, while skip = 1 correctly parses the file.

The colon is the default separator. At times other separators may be used to separate speaker and text. Here is an example where hypens are used as a separator. Notice the poor parse with colon set as the default separator the first go round.

Pairing textreadr

textreadr is but one package used in the text analysis (often the first package used). It pairs nicely with a variety of other text munging and analysis packages. In the example below I show just a few other package pairings that are used to extract case names (e.g., "Jones v. State of New York") from a Supreme Court Database Code Book. I demonstrate pairings with textshape, textclean, qdapRegex, and dplyr.

if (!require("pacman")) install.packages("pacman"); library(pacman)
p_load(dplyr, qdapRegex)
p_load_current_gh(file.path('trinker', c('textreadr', 'textshape', 'textclean')))

## Read in pdf, split on variables
dat <- 'http://scdb.wustl.edu/_brickFiles/2012_01/SCDB_2012_01_codebook.pdf' %>%
    textreadr::download() %>%
    textreadr::read_pdf() %>%
    filter(page_id > 5 & page_id < 79) %>%
    mutate(
        loc = grepl('Variable Name', text, ignore.case=TRUE),
        text = textclean::replace_non_ascii(text)
    ) %>%
    textshape::split_index(which(.$loc) -1) %>%
    lapply(select, -loc)

## Function to extract cases
ex_vs <- qdapRegex::ex_(pattern = "((of|[A-Z][A-Za-z'.,-]+)\\s+)+([Vv]s?\\.\\s+)(([A-Z][A-Za-z'.,-]+\\s+)*((of|[A-Z][A-Za-z',.-]+),?($|\\s+|\\d))+)")

## Extract and filter cases
dat %>%
    lapply(function(x) {
        x$text %>%
            textshape::combine() %>%
            ex_vs()  %>% 
            c() %>% 
            textclean::mgsub(c("^[ ,]+", "[ ,0-9]+$", "^(See\\s+|E\\.g\\.?,)"), "", fixed=FALSE)
    }) %>%
    setNames(seq_along(.)) %>%
    {.[sapply(., function(x) all(length(x) > 1 | !is.na(x)))]}
