[R] Setting two default CRAN servers under Windows/RStudio

[Thierry Onkelinx]

We have this in our Rprofile.site This works fine. It checks each mirror
and installs (or updates) the latest version available on all mirrors. e.g.
abc 0.1 on RStudio and abc 0.2 on RForge, then abc 0.2 from RForge gets
installed/updated.

options(
  repos = c(
    RStudio = "http://cran.rstudio.com/",
    RForge = "http://r-forge.r-project.org",
    Belgium = "http://www.freestatistics.org/cran/",
    CRAN = "http://cran.at.r-project.org/",
    Oxford = "http://www.stats.ox.ac.uk/pub/RWin"
  ),
  install.packages.check.source = "no"
)

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to say
what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of data.
