With the objective of including data from RSS feeds into your analysis, 'tidyRSS' parses RSS, Atom and JSON feeds and returns a tidy data frame.
tidyRSS is a package for extracting data from RSS feeds, including Atom feeds, JSON feeds and georss feeds.
It is easy to use as it only has one function,
tidyfeed(), which takes
two arguments, the url of the feed and a logical flag for whether you
want a geoRSS feed returned as a simple features dataframe or not.
Running this function will return a tidy data frame of the information
contained in the feed. If the url is not an rss or atom feed, it will
return an error message.
Included in the package is a simple dataset, a list of feed urls, which
you can use to experiment with. You can access this with
It can be installed directly from CRAN with:
The development version can be installed from GitHub with the devtools package.
RSS feeds can be parsed with
tidyfeed(), and some examples are
included in the “feeds” dataset. Here is an example of using the
library(tidyRSS)data("feeds")# select a feed:rss <- sample(feeds$feeds, 1)tidyfeed(rss)#> # A tibble: 50 x 5#> feed_title feed_link item_title item_date_published item_link#> <chr> <chr> <chr> <dttm> <chr>#> 1 Instructab… … All You Nee… 2018-07-04 10:03:03 …#> 2 Instructab… … Automatic Ra… 2018-07-04 09:35:14 …#> 3 Instructab… … DIY survival… 2018-07-04 09:27:17 …#> 4 Instructab… … Recycled and… 2018-07-04 08:29:32 …#> 5 Instructab… … ESP8266 Temp… 2018-07-04 08:23:55 …#> 6 Instructab… … How to Cool … 2018-07-04 06:58:42 …#> 7 Instructab… … DIY Laundry … 2018-07-04 06:38:56 …#> 8 Instructab… … DIY Li-ion C… 2018-07-04 05:54:44 …#> 9 Instructab… … Aluminum Cas… 2018-07-04 04:55:02 …#> 10 Instructab… … Receipt hold… 2018-07-04 04:44:50 …#> # ... with 40 more rows

RSS & Atom XML feeds can be finicky things, if you find one that doesn’t
tidyfeed(), let me
know. Please include the
url of the feed that you are trying. Pull requests and general feedback
are welcome. Many feeds are malformed. What this means is that, for a
well-formed feed, you’ll get back a tidy data frame with information on
the feed and the individual items (like blog posts, for example),
including content. For malformed feeds, it will be less than this, as
NA columns, where the information wasn’t in the
feed in the first place.
The package is a ‘tidy’ version of two other related packages, rss and feedeR, both of which return lists. In comparison to feedeR, tidyRSS returns more information from the RSS feed (if it exists), and development on rss seems to have stopped some time ago.
For an example Shiny app that uses geoRSS, see here.
Changes: Added funcionality to process dc:date tags in v1 RSS feeds and better handling of item category columns, see https://github.com/luke-a/tidyRSS/commit/c677022996fa971b49ef1a858ae21ca720b56c8e .
Changes: Fix to add proper href links in Atom feeds.
Changes: Small fix to add item descriptions for RSS feeds.
Changes: Fixed an error with feeds parsing as geoRSS when they didn't have the necessary lat/lon columns.
Changes: Removed tests. The tests were based on checking a bunch of RSS feed URLs. Since feeds undergo maintenance, or are taken down etc., the tests were failing randomly.
Changes: Added support for geo RSS feeds.
Changes: Changed tests to avoid failures due to problems outside the package (faulty connections, site maintenance, feeds being taken down).
Changes: Added preliminary support for jsonfeeds; minor changes to parsing other feeds; minor change to data included with the package.
Changes: Minor changes to parsing Atom feeds.
