You don't need to use command line tools -- I showed how to do it by
creating an R Markdown document with each page of the PDF on a numbered
page of the result.
Here's a minor improvement of my post:
---
title: "Numbered"
output:
pdf_document:
extra_dependencies: ["pdfpages", "fancyhdr", "lastpage"]
---
\cfoot{Page \thepage\ of \pageref{LastPage}}
\addtocounter{page}{-1}
\includepdf[pages={1-},pagecommand={\thispagestyle{fancy}}]{Rplots.pdf}
This works regardless of the number of pages in Rplots.pdf.

But what about the idea of creating a PDF with a placeholder like "Page N

XXX" and after the file has been created, dates and all, perhaps edit it
programmatically and replace all instances of XXX with something of the
same
length like " 23" as there seem to be tools like the pdftools package that
let you get the number of pages. I have no idea if some program, perhaps
external, can do that and retain the date you want.

Subject: [R] adding "Page X of XX" to PDFs
OS X
R 4.3.1
Colleagues
I often create multipage PDFs [pdf()] in which the text "Page X" appears in
the margin. These PDFs are created automatically using a massive R script.
One of my clients requested that I change this to:
Page X of XX
where XX is the total number of pages.
I don't know the number of expected pages so I can't think of any clever
way
to do this. I suppose that I could create the PDF, find out the number of
pages, then have a second pass in which the R script was fed the number of
pages. However, there is one disadvantage to this -- the original PDF
contains a timestamp on each page -- the new version would have a different
timestamp -- so I would prefer to not use this approach.
Has anyone thought of some terribly clever way to solve this problem?

You could easily omit the Page X of xX, but leave the timestamp Then add Page X of XX programmatically using pdftools or some similar pdf command line tools.

I agree with that comment. However, if one is stuck with a multipage
PDF file, and wants to add page numbering, you could use the LaTeX
pdfpages package.
For example, this R Markdown document includes all 10 plots from
Rplots.pdf on pages with "x of y" page numbering.

\includepdf[pages={1-10},pagecommand={\thispagestyle{fancy}}]{Rplots.pdf}
It would make more sense to do this in a LaTeX document, but I'm not
sure if Dennis knows LaTeX...

Re: [R] adding "Page X of XX" to PDFs
One of the most fundamental characteristics of R programming is the use of data frames of column vectors, and one of the very first challenges I had as a then-Perl-programmer was coming to grips with the fact that unknown-length CSV files would be read completely into memory as rows and once the entire CSV was in memory it would be transposed into column vectors. I was resistant to this philosophy at first, but the advantages in computation speed and simplicity eventually won me over. I would say that if you want to know how many pages you are going to produce with R, then you are going to have to count them before you create them. Building a dataframe that describes (in terms of parameters to be passed to a page-generating function in each row) what you are going to put on each page before you actually print it can make this pre-counting problem trivial, and the code that does the printing is likely to be more modular and testable as well.

Can you provide a very simplified version of how the PDF is created?

[R] adding "Page X of XX" to PDFs
OS X R 4.3.1 Colleagues I often create multipage PDFs [pdf()] in which the text "Page X" appears in the margin. These PDFs are created automatically using a massive R script. One of my clients requested that I change this to: Page X of XX where XX is the total number of pages. I don't know the number of expected pages so I can't think of any clever way to do this. I suppose that I could create the PDF, find out the number of pages, then have a second pass in which the R script was fed the number of pages. However, there is one disadvantage to this -- the original PDF contains a timestamp on each page -- the new version would have a different timestamp -- so I would prefer to not use this approach. Has anyone thought of some terribly clever way to solve this problem?
