Examples

f <- pdf_create_blank(length = 8L)
pdf_pages(f, pages = 1:4)
#> [1] 1 2 3 4
pdf_pages(f, pages = -(1:4))
#> [1] 5 6 7 8
pdf_pages(f, pages = "all")
#> [1] 1 2 3 4 5 6 7 8
pdf_pages(f, pages = "even")
#> [1] 2 4 6 8
pdf_pages(f, pages = "odd")
#> [1] 1 3 5 7
pdf_pages(f, pages = "interleave")
#> [1] 1 5 2 6 3 7 4 8
pdf_pages(f, pages = "interleave_first")
#>  [1] 1 2 1 3 1 4 1 5 1 6 1 7 1 8
