PDE_analyzer {PDE}

Extracting data from PDF (Portable Document Format) files

Description

The PDE_analyzer allows the sentence and table extraction from multiple PDF files.

Usage

PDE_analyzer(PDE_parameters_file_path = NA, verbose = TRUE)

Arguments

PDE_parameters_file_path

String. This file includes all parameters to run PDE_extr_data_from_pdfs on multiple PDF files. If PDE_parameters_file_path does not exist or is NA a dialog box is opened prompting the user to select the parameter file.

verbose

Logical. Indicates whether messages will be printed in the console. Default: TRUE.

Value

If tables were extracted from the PDF file the function returns a list of following tables/items: 1) htmltablelines, 2) txttablelines, 3) keeplayouttxttablelines, 4) id, 5) out_msg. The tablelines are tables that provide the heading and position of the detected tables. The id provide the name of the PDF file. The out_msg includes all messages printed to the console or the suppressed messages if verbose=FALSE.

Details

The parameter file (also referred to as .tsv file) can either manually or with the help of the PDE_analyzer_i interface be filled.

Note

A detailed description of the parameters in the TSV file can be found in the markdown file (README_PDE.md) and in the description of PDE_extr_data_from_pdfs.
