There's more…

There is another way to read a PDF file into the R environment. The tm library has a wrapper function called readPDF(). This function actually does not read the PDF document, rather it creates a function to read the PDF document. The typical structure of the readPDF() wrapper function is as follows:

    readPDF(engine, control=list())

For more details on this function, you are directed to the documentation of the readPDF() function from the tm library.
