Programmatically collect normalized news from (almost) any website using R
newscatcheR is an R clone of the python package newscatcher.
The package provides a dataset of news sites and their rss feeds,
together with some characteristics of the websites such as the topic,
country or language of the website, and few functions explore and access
the feeds from R.
Two functions that work as a wrapper around tidyRSS can be used to fetch the feed from a given website. Two additional functions can be used to conveniently browse the websites dataset.
You can install the released version of newscatcheR from CRAN with:
install.packages("newscatcheR")And the development version from GitHub with:
# install.packages("remotes")
remotes::install_github("discindo/newscatcheR")Or
# install.packages("devtools")
devtools::install_github("discindo/newscatcheR")get_news(website) returns the contents of a rss feed of
a website.

Assuming we have the news sites we want to follow:
sites = c("bbc.com", "spiegel.de", "washingtonpost.com")We can get a list of data frames with:
library(newscatcheR)
lapply(sites, get_news)These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
