As you might know, selecting a CRAN mirror normally uses tcltk. Most likely something is wrong with tcltk (not the R package, but the library) on your machine.

This is unrelated to the bug above. In newer versions of R, the X11 device uses type = "cairo" per default. This gives prettier results, but is slower on (some) network connections.

Use X11(type = "Xlib") before you issue your plot command. This usually results in substantial speedup. This is an old issue, that has been discussed at depth when type = "cairo" was set to be default.
