Note: R allows for the download of any file format you want. In the previous example, we have downloaded a csv file. Furthermore, it is possible to download files from a sharepoint or a web application such as shiny. Do you need further guidance for the downloading of files from the web?

What happens to the destination file s in the case of error depends on the method and R version. Currently the "internal" , "wininet" and "libcurl" methods will remove the file if there the URL is unavailable except when mode specifies appending when the file should be unchanged.
This is usually done using the CA root certificates installed by the OS although we have seen instances in which these got removed rather than updated. Note that the root certificates used by R may or may not be the same as used in a browser, and indeed different browsers may use different certificate bundles there is typically a build option to choose either their own or the system ones.
The "libcurl" methods uses passive mode, and that is almost universally used by browsers. Setting the method should be left to the end user. Neither of the wget nor curl commands is widely available: you can check if one is available via Sys. If you use download. The supported method s do change: method libcurl was introduced in R 3. Files of more than 2GB are supported on bit builds of R ; they may be truncated on some bit builds.
Methods "wget" and "curl" are mainly for historical compatibility but provide may provide capabilities not supported by the "libcurl" or "wininet" methods. Windows binaries are available from Cygwin, gnuwin32 and elsewhere.

Can you specify your operating system and version of R? The mode parameter is only used when the internal method is used. The default method is auto so I suspect that it may depend on the OS.
I have no problem in downloading the file using R 3. I think probably it's to do with how the ISP transmits http binary streams, which would explain why it works for some people without enforcement of mode and not for others. RStudio Version 0.
