chooseBioCmirror {utils}R Documentation

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))

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).

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.
