How to convert an HTML R object to character?

Here's my reproducible example:

library(rvest)
page <- html("http://google.com")
class(page)
page
> as.character(page)
Error in as.vector(x, "character") : 
  cannot coerce type 'externalptr' to vector of type 'character'

How can I convert page from an html class to a character vector so I can store it somewhere?

The html functions like html_text or html_attr don't give me the whole source. I would like to store it so I can later re-load it with html().

Thanks.

Solution

  • To save directly to a text file:

    capture.output(page, file="file.html")

    To store as a string:

    htmltxt <- paste(capture.output(page, file=NULL), collapse="\n")
