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.

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 http://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.

Value

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

Note

The online list of mirrors is always accessed using HTTPS. If your build of R does not support HTTPS, R uses the local copy in ‘R_HOME/doc/BioC_mirrors.csv’. It can be updated from https://bioconductor.org/BioC_mirrors.csv.
