convPDFs: Convert PDF to Text Files

In madlogos/asestio: ASES Analytic Toolkit on Data I/O and Transformation

Description

Use Xpdf to convert PDFs to text files. The function relies on doParallel to convert the PDFs in parallel. It calls Xpdf to complete the conversion. Currently this function only supports Windows.

Usage

convPDFs(mode = 1L, silent = FALSE, converter = c("pdftotext",
  "pdftohtml"), converter.path = NULL, use.parallel = TRUE)

conv_pdfs(mode = 1L, silent = FALSE, converter = c("pdftotext",
  "pdftohtml"), converter.path = NULL, use.parallel = TRUE)
