Sure are, but you need to download and install them, e.g. via the
ActiveState Tcl binaries if you're on Windows. You also need to tell R about
it using the MY_TCLTK env.variable.

James Wettenhall's treasure of a site for R/tcltk has examples (though his
may be for Bwidgets), the mechanics is the same.

A simple self-contained example using the IWidgets calendar widget follows.

library(tcltk)
tclRequire("Iwidgets")
tt <- tktoplevel()
cal <- tkwidget(tt, "iwidgets::calendar")
tkconfigure(cal, command=function(...)cat(tclvalue(tkget(cal))))
tkpack(cal)
