graphics |
Logical. If true, use a graphical list: on Windows or
Mac OS X GUI use a list box, and on a Unix-alike if package
tcltk and an X server are available, use a Tk
widget. Otherwise use a text |
all |
Logical, get all known mirrors or only the ones flagged as OK. |
local.only |
Logical, try to get most recent list from CRAN or use file on local disk only. |

This function was originally written to support a Windows GUI menu

initial dummy value of options("repos").
None for chooseCRANmirror(), this function is invoked for its
side effect of updating options("repos").
getCRANmirrors() returns a data frame with mirror information.
