update dataframe automatically

Is there a way to update a data frame downloaded from a website? I want the data frame to be updated from the website directly without downloading each time. Can anyone help for the same?

Hi Gavin,

Try web scraping to download the file from the website directly while running r script.

Extract the content from the webpage directly into the data frame while running the page.
