Is there an R command to trigger the download of a file from Rstudio Server?

问题

When working with Rstudio Server, it is very easy to download a file from the server with File>More>Export... The web browser will automatically start downloading.

Is there a way to generate this download with an R command ?

Does browseURL do it for you:

browseURL                package:utils                 R Documentation

Load URL into a WWW Browser

Description:

     Load a given URL into a WWW browser.

Usage:

     browseURL(url, browser = getOption("browser"), encodeIfNeeded = FALSE)

That should fire it up in a browser. To download directly in R, download.file is what you want, but that hangs the command line until complete.
