chooseBioCmirror: Select a Bioconductor Mirror

Description

Interact with the user to choose a Bioconductor mirror.

Usage

chooseBioCmirror(graphics = getOption("menu.graphics"), ind = NULL,
                 useHTTPS = getOption("useHTTPS", TRUE),
                 local.only = FALSE)

Arguments

graphics
Logical. If true, use a graphical list: on Windows or the OS X GUI use a list box, and on a Unix-alike use a Tk widget if package tcltk and an X server are available. Otherwise use a text menu.
ind
Optional numeric value giving which entry to select.
useHTTPS
Whether to prefer HTTPS mirrors (see chooseCRANmirror).
local.only
Logical, try to get most recent list from the Bioconductor master or use file on local disk only.

Value

  • None: this function is invoked for its side effect of updating options("BioC_mirror").

Details

This sets the option "BioC_mirror": it is used before a call to setRepositories. The out-of-the-box default for that option is NULL, which currently corresponds to the mirror https://bioconductor.org.

The Bioconductor (World-wide) mirror is a network of mirrors providing reliable world-wide access; other mirrors may provide faster access on a geographically local scale.

ind chooses a row in R_HOME/doc/BioC_mirrors.csv, by number.
