Thanks for your reply. Actually my problem is not how to install the
libraries in the sense of copying them to the right place, but how to
build more than one .so or .dll file. Anyway, I did read the code and
found that absence of a Makefile, a single library is built from all
source files in d

Dear List,
I recently stumbled over the possibility and need to specifiy

I have some questions with regards to that:

Just found in the documentation for getHook that packages are not
unloaded on quit. How should I force a package to unload on quit?

Hi,
I'd like to plot a tree with images of molecular structures instead of
labels (words). I think this is possible because someone who worked in my
office before I arrived did this. However I'm not sure if this person made
the image manually or plotted it only with R.
Thanks in advance for your

We've tried to contact Stig since July. Possibly he changed emails.
My thought was to use Rprintf as suggested and was looking into doing that to
see if our
optimx problems would go away. Will keep it as open issue while we give a bit
more time
for response, and welcome input from others.

My reaction is leaning heavily towards "Virtuoso!" as opposed to "Show Off!".
Thanks very much.

You create your own .Last - there is nothing to overwrite.
