>From what I can glean from the sources and bundled packages, the tcltk
package isn't built by default for the MacOS port of R. Looking at the code
there doesn't seem to be any real reason not to do this except that perhaps
tcl/tk isn't available on the builders machine. Is this the case?
Since I have a need for cross platform access to tcltk from R, and since I
have one of the Mac Tcl maintainers working with me, I plan to build this
package at least for our own purposes. I can make it available to others if
there is a demand.
I also wonder whether anyone has done anything about passing data between tcl
and R. I need to pass lists of things back and forth and although it seems I
can do this via strings it will introduce a lot of overhead when they are
long. I haven't looked at R internals much but would it be hard to code for
special cases like passing a vector of strings or a vector of doubles?
My interest here is making some signal processing and speech database
functionality available in R which is already available as tcl extensions.
