Many legal documents are in fact in .pdf and not in .txt format. To upload those we will use the package “pdftools”.
# Activate package
It is important to note that only pdfs with embedded digital texts can be uploaded. Scanned images of a text first need to undergo OCR – Optical Character Recognition. Today, we will work with the Universal Declaration of Human Rights as an example.
# Download a .pdf version of the Universal Declaration of Human Rights directly into R from the internet.
human_rights <- pdf_text("https://www.ohchr.org/EN/UDHR/Documents/UDHR_Translations/eng.pdf")
The pdf_text() function converts each page into an element in your object. The Universal Declaration is 8 pages long. It has thus been converted into a list with 8 elements.
# If we want to look at page 5, simply specify the number of that page.
