xgobi/ggobi

Hello,

R 1.2.0 / Win98

I just downloaded the Win version of Rggobi from http://www.ggobi.org/
and installed it with Rwinst. When I tried to load the library, I got
the following error message:

library(rggobi)

Error in dyn.load(x, as.logical(local), as.logical(now)) :
        unable to load shared library
"E:/PROGRAMS/R/RW1020/library/rggobi/libs/Rggobi.dll":
  LoadLibrary failure:  Une des bibliothèques nécessaires à l'exécution
de cette application n'a pu être trouvée.
Error in library(rggobi) : .First.lib failed

I rebooted my computer but the problem still occurred. I checked in the
rggobi/libs directory, and Rggobi.ddl is there. Does anyone know how to
fix this ?

You should have got a dialog box up saying that some (specific) other DLL
could not be found.  Do you have the winggobi\bin folder in your PATH? It
might suffice to have a recent verion of GIMP installed, as that will
install the needed DLLs, I believe.

There seem to be quite a few things wrong with that Rggobi.zip:
the DESCRIPTION is wrong and INDEX and TITLE are missing for a start.

From the installation instructions the version of libxml used is one

known not to work properly on Windows (from the changes log in the
current libxml2), so don't expect too much of xml support.

Running from rterm.exe there are severe event-loop problems: the ggobi
window does not respond except when rterm is not waiting for a prompt.

Running from rgui.exe I got crashes on almost everything I tried.
example(ggobi) fails to find two data files, and

library(Rggobi)
data(mtcars)
ggobi(mtcars)

came up but crashed (in its own DLL) as soon as I selected anything.

I concluded this was at best a beta.  Standalone winggobi worked under
some brief tests, albeit much slower than xgobi (using Exceed 6.2 to
display) on the same machine.

This might be better discussed on the ggobi help list, but I failed to
subscribe to that as mail to ggobi.org is refused ....
