[R] Function gutenberg_download in the gutenbergr package

[Patrick Connolly]

I've been working through https://www.tidytextmining.com/tidytext.html
wherein everything worked until I got to this part in section 1.5

> hgwells <- gutenberg_download(c(35, 36, 5230, 159))
Determining mirror for Project Gutenberg from http://www.gutenberg.org/robot/harvest
Error in open.connection(con, "rb") : 
  Failed to connect to www.gutenberg.org port 80: Connection timed out

Which indicates the problem is at the very start:

  if (is.null(mirror)) {
    mirror <- gutenberg_get_mirror(verbose = verbose)
  }

The documentation for gutenberg_get_mirror indicates there's nothing
different I could set.

So I tried specifying my usual mirror:

> hgwells <- gutenberg_download(c(1260, 768, 969, 9182, 767), mirror = "http://cran.stat.auckland.ac.nz")
Error in read_zip_url(full_url) : could not find function "read_zip_url"
> 

Which is, indeed, strange since according to 

> help.search("read_zip_url")
Help files with alias or concept or title matching ‘read_zip_url’ using
regular expression matching:


gutenbergr::read_zip_url
                        Read a file from a .zip URL
  Aliases: read_zip_url

[...]

And according to 
library(help = "gutenbergr")

[...]
Index:

gutenberg_authors       Metadata about Project Gutenberg authors
gutenberg_download      Download one or more works using a Project
                        Gutenberg ID
gutenberg_get_mirror    Get the recommended mirror for Gutenberg files
gutenberg_metadata      Gutenberg metadata about each work
gutenberg_strip         Strip header and footer content from a Project
                        Gutenberg book
gutenberg_subjects      Gutenberg metadata about the subject of each
                        work
gutenberg_works         Get a filtered table of Gutenberg work metadata
read_zip_url            Read a file from a .zip URL

[...]

However, when I look at the list for that part of the search(), there
is no read_zip_url but all the rest of that list are present.  So it's
not surprising that it isn't found.  But it puzzles me that it is not
there.

Ideas as to where I should proceed gratefully appreciated.
