How to use R to download file from internet ?

In this article, we will be looking at the approach to download any type of file from the internet using R Programming Language. To download any type of file from the Internet download.file() function is used. This function can be used to download a file from the Internet.

Syntax: download.file(url, destfile, method, quiet = FALSE, mode = "w", cacheOK = TRUE, extra = getOption("download.file.extra"),headers = NULL, …)

Parameters:

• URL:-a character string (or longer vector e.g., for the "libcurl" method) naming the URL of a resource to be downloaded.
