Description

Build a dataframe with the input number of the most frequent words in the article (word frequency in decreasing order) Plot it with a wordcloud (optional)

Usage

analyze_text(url_end, num_word, do_plot = FALSE)

Arguments

url_end	character string, an ending part of BBC News particular atricle URL (everything after https://www.bbc.com/news/). For example, article URL is "https://www.bbc.com/news/world-us-canada-51381625". Only "world-us-canada-51381625" should be pasted
