If you update to R-patched, you'll see the difference. With current
releases of R, you'll see some mirrors twice: the first one is https,
the second is http.
The other issue you may have is that your system may be configured to
default to a method that doesn't support https. Try
download.file("https://cran.rstudio.com";) and
readLines(url("https://cran.rstudio.com";)) to confirm that's not a
problem for you.
