In Defenders-ESC/pdfdown: Robust Downloads of Portable Document Format (PDF) Files
pdfdown
An R package to simplify Portable Document Format (PDF) file downloads.
Scraping PDFs from the web can run into little hitches that make writing a
scraper annoying. This simplifies PDF scraping by creating a dedicated function
and support functions to, e.g., test for PDFness. Ensures URL encoding, handles
missing URLs gracefully. The main function, download_pdf, includes the
pause parameter (random 0-3s) to limit the rate at which requests hit the
host server. We mostly use this to facilitate scraping U.S. Government documents
that are only available as PDFs.
Installation
Use devtools to install pdfdown:
devtools::install_github("Defenders-ESC/pdfdown")
Usage
