R - adding page numbers to PDF

Question

I\'m having trouble adding page numbers to PDFs. Here\'s how I\'m inserting pages / plots:

pdf( file = pdfFilePath , width = 11 , height = 8.5  )
for ( ...          


        

Answer 1

library(ggplot2)
plots = replicate(8, qplot(1,1))
library(gridExtra)
p <- 
do.call(marrangeGrob, c(plots, list(ncol=2, nrow=2, top =NULL, 
        bottom = quote(quote(paste(g, "/",pages))))))

p

ggsave("multipage.pdf", p)

(the quote(quote()) is needed to maintain lazy evaluation, somehow)
