| chooseCRANmirror | R Documentation |
Interact with the user to choose a CRAN mirror.
chooseCRANmirror(graphics = getOption("menu.graphics"), ind = NULL,
local.only = FALSE)
getCRANmirrors(all = FALSE, local.only = FALSE)
graphics |
Logical. If true, use a graphical list: on Windows or
the macOS 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 |
ind |
Optional numeric value giving which entry to select. |
all |
Logical, get all known mirrors or only the ones flagged as OK. |
local.only |
Logical, try to get most recent list from the CRAN master or use file on local disk only. |
A list of mirrors is stored in file ‘R_HOME/doc/CRAN_mirrors.csv’, but first an on-line list of current mirrors is consulted, and the file copy used only if the on-line list is inaccessible.
This function is called by a Windows GUI menu item and by
contrib.url if it finds the initial dummy value of
options("repos").
HTTPS mirrors with mirroring over ssh will be offered in
preference to other mirrors (which are listed in a sub-menu).
ind chooses a row in the list of current mirrors, by number. It
is best used with local.only = TRUE and row numbers in
‘R_HOME/doc/CRAN_mirrors.csv’.
None for chooseCRANmirror(), this function is invoked for its
side effect of updating options("repos").
getCRANmirrors() returns a data frame with mirror information.
