I am using the pdftools package to read in a pdf file in R.

I've used the following code which works for the 1 pdf file I have (although it is designed to read in multiple files from my wd if needed):

    files <- list.files(pattern = "pdf$")
    mypdf <- lapply(files, pdf_text)
    corp <- Corpus(URISource(files),
               readerControl = list(reader = readPDF))

How can I select specific pages from my 1 pdf (or a specific pdf) within my files/wd? e.g. I only want to read in pages 10:16

I tried applying brackets [10:16] after pdf_text(), but this didn't work

You are saving your PDFs to a list, so that's why the brackets aren't working as expected. mypdf[10:16] would work if your object was a single PDF, but since you have multiple PDFs in a list, you need to use lapply:

lapply(mypdf, \(x) x[10:16])
