R devel - Apr 2005 - pl/R and MacOS X using R binary

I'm sorry if this is too off-topic--feel free to ignore.  I am 
interested in using pl/R, an amazing "plugin" for the postgresql 
database.  As is typical of these types of applications, pl/R needs to 
link against a shared library.  However, it appears that the MacOS R 
binary does not build a static (.so) shared library.  Is there an 
accepted, general way (read, a way that works) for linking against R 
(presumably the dylib) on the Mac?

Thanks,
Sean

Excuse me, but a .so is a DSO, a Dynamic _Shared_ Object.  What does 
`static' have to do with this?  libR is a dynamic library, actually 
libR$(DYLIB_EXT) with values of .so. .sl and .dylib being known.

Yes, since that is how the GUI on MacOS X works.

My guess is that you think that pl/R requires libR.so: if correct that is 
a false assumption made somewhere along the line, and the best thing to do 
is to consult the author.  In any case

http://www.joeconway.com/plr/doc/plr-install.html

just says

   Tip:  R headers are required. Download and install R prior to building
    PL/R. R must have been built with the --enable-R-shlib option when it
    was configured, in order for the libR shared object library to be available.


Please do consult the posting guide as to the right place.  (I've moved 
this to R-devel and included Joe Conway. Joe: perhaps you could make you 
email address more readily available in the PL/R pages.)

Hi,

Sorry if the answer is really simple. But I'm looking for a expandable 
tree visualisation (like file organisation with plus or minus sign on 
the left to expand the tree). As the file is quite big. ~12000 rows. 
and with possible 5 layers (so there are index numbers like 1.1.1.1.1 
to make then into different classes). I programmed in tk and ggobi, 
both are very slow as it loads the data all at once and cost about 5 
seconds just to load 2000 files. Is there an automatic way of doing 
this?

Many thanks.
