Reading a .txt file in R

I'm having trouble thinking about the approach on reading a text file. I initially had a PDF file (700 pages worth of table formatted same exact way) which I then converted to a .txt file using the pdftools package.

The text file I end up getting has a bunch of texts (comments) that are not needed and then the table of 8 records and then it repeats itself on and on (see attached file).

Would greatly appreciate any direction on this.
