tcltk

| (Another question about my incomplete configuration.)
| 
| I thought I had everything working with my Ubuntu 8.10 64bit, but I 
| still seem to be missing tcl/tk:
| 
|  > require("tcltk")
| Loading required package: tcltk
| Error in firstlib(which.lib.loc, package) :
|    Tcl/Tk support is not available on this system
| 
| 
| Synaptic shows tcl and tk both installed, and I have r-base and 
| r-base-dev installed.  How do I find what is missing?

Did you build R by hand?  The prebuild packages have working tcltk:

deddelbuettel at ....:~$ echo "capabilities()"|R --slave
    jpeg      png     tiff    tcltk      X11     aqua http/ftp  sockets
    TRUE     TRUE     TRUE     TRUE     TRUE    FALSE     TRUE     TRUE
  libxml     fifo   cledit    iconv      NLS  profmem    cairo
    TRUE     TRUE    FALSE     TRUE     TRUE     TRUE     TRUE

amd64, Ubuntu intrepid, Ubuntu R binaries from CRAN.

Yes, I built from the tarball (./configure ; make ).

To answer my own question, building requires the header files in tcl-dev 
and tk-dev.  The fact that they were missing was buried in the output of 
  configure.  Perhaps tcl-dev and tk-dev should be dependencies in 
r-base-dev? (Or perhaps they are and it is still just me getting an old 
version.)

No, sorry. As I said just yesterday, the purpose of r-base-dev is to
facilitate use of installed.packages() once R is up, and not for building R.

What you are after is provided (correctly) by Build-Depends: in the r-base
package.

You could

  a) either just install the r-base binaries as I suggested yesterday

  b) or at least take advantage of the Build-Deps via 
       sudo apt-get build-dep r-base

I am sorry if this is still confusing. We would all appreciate patches to the
README files if you can find a way to express this more clearly.

Hope this helps, Dirk
