There are some warnings earlier in the log about my .Rd files (missing a

Error in firstlib(which.lib.loc, package) :
Tcl/Tk support is not available on this system
I'm also curious about this. But I get the same aareg error on the Sun server
at work, without the Tcl message, so I know it is not primary.
The most obvious reason would be if Tcl/Tk support is not available on
your system....
(a) Which system?
(b) Do you have
capabilities("tcltk")
tcltk
TRUE
Because so many people assume that tcltk is present, those checks look
for unexplained symbols in package tcltk. As it is not on your
system, you will not be able to use the symbols and it does not
matter. The call is inside try(), so the error is ignored.
