title: Disable/suppress tcltk popup for CRAN mirror selection in R
body: <p>My question is similar to a question previously posted but never really answered here:</p>

  <p>I do not like the R tcltk popups for CRAN mirror selection. They also pop up to choose a package when searching for help on a function in two packages.</p>
  
  <p>Is there any way to disable these windows without disabling X11 completely? I still want plot() commands to work as normal, but disable the little select menus that take forever to load over a remote connection.</p>
  
  <p>For example, if you use ssh, but don't use -X, then the mirror select is just text within R, you type a number. It's fast. This is what I want, but maintaining X11 for plots b.</p>
  
  <p>Anyone know how to maintain graphics windows but disable the "choice" tcltk windows?</p>
