KNIME_join_pdf_using_r_with_variables

Workflow to demonstrate using R snippet for joining two pdf files.

This workflow is based on my proof of concept workflow but now takes the file details FilePath1, FilePath2 and JoinedFilePath from the File Details in the Table Creator.

This converts the three supplied values into table variables which are then fed to the R snippet. The R Snippet does not make use of the File Details table, but this is passed because it does require an input data flow.

The R Snippet uses the qpdf package which must be installed in your R environment for this to work. You (may) also need to install the pdftools package in your R environment.
