How to select a CRAN mirror in R

I'm trying to install a package through the R prompt by doing the following:

install.packages('RMySQL')

But the output is as follows: 

--- Please select a CRAN mirror for use in this session ---

And nothing else! I can't find a solution to this very basic problem. What am I supposed to type in order to select a CRAN mirror?

EDIT:

OS: Mac-OS X 10.6.8 R Version: 2.15.0

cran r installation package

You could also disable all graphical menus by running this or placing it in your Rprofile

options(menu.graphics = FALSE)

I had, on macOS, the exact thing that you say: A 'please select' prompt and then nothing more.

After I opened (and updated; don't know if that was relevant) X-Quartz, and then restarted R and tried again, I got an X-window list of mirrors to choose from after a few seconds. It was faster the third time onwards.

Add into ~/.Rprofile

local({r <- getOption("repos")
    r["CRAN"] <- "mirror_site"  #for example, https://mirrors.ustc.edu.cn/CRAN/
    options(repos=r)
    options(BioC_mirror="bioc_mirror_site") #if using biocLite
})
