Mirror, mirror on the wall, who's the fairest of them all?
- quote from the fairy tale Snow White aka Schneeflittchen :-D


Dear ElMaestro, Helmut and others,

❝ I actually also install from CRAN directly.


CRAN is actually a network AFAIK. Consisting of the main mirror http://cran.r-project.org hosted in Vienna, I think, an great number of mirrors all over the world. See them at http://cran.r-project.org/mirrors.html.

What the people at RStudio.com do is to make available log-files of downloads from their own server(s) - they speak from a cloud, whatever this is :-D - mirroring the CRAN content.
In the R GUI you will be asked to choose a mirror if you install a package.
In RStudio the mirror is predefined as CRAN.RStudio.com. But you may change it.

So directly downloading from CRAN is not a reasonable term.
And using RStudio is not necessary to have your footprint in the logs. Just choose the RStudio mirror while installing or updating packages. It is the first entry in the list of mirrors you get if you install via R GUI, named 0-cloud.
See also this blog entry.

[edit]Do all the R and package developers the favour and change your mirror to the 0-cloud. The faintest of all :cool:.[/edit]

Regards,

Detlew
