.Random.seed(0) is not a valid Normal type

Dear R-Developers and -Community,

after compiling and installing R 1.2.2., I started 'demo(graphics)' for
a test, and got:

'Error in rnorm(0): .Random.seed(0) is not a Normal type'

Obviously .Random.seed was not initialized appropriately. Following the
the documentation for '.Random.seed' [see below 'Examples'], this can be
fixed 
          rm(.Random.seed); runif(1); .Random.seed 

and all seems to work nicely.

But two questions remain:
- was this my fault, is it intended, or are corrections inside R necessary ?
- are there any other objects in R, which unintentionally are not initialized
  at start?  (This may lead to unobserved errors.)

      Thank you for a great System !!   Best wishes - Hartmut Oldenbürger

This doesn't normally happen. Did you by any chance load an old
workspace (.RData) on startup? 

If it is reproduceable, then we'd like to have the instructions to
reproduce it as well as some information about which system you're
running it on.

FYI

The ggobi interface for both Linux and Windows have been available at
http://www.ggobi.org/
for several weeks now. Both versions come with an R interface library 
(Rggobi, apparently to be RSggobi when the Splus version is finalised).

"GGobi is a data visualization system for viewing high-dimensional data and 
is the next
        edition of xgobi. It provides a new interface to many of the 
features of xgobi, built
        using Gtk, the GIMP toolkit and provides several new features:
             A new, simpler and more modern interface.
             Better portability to PCs.
             Direct access from R Perl and Python
             New input format using XML.
             Database (MySQL) support. "

More expert users may wish to comment and advise the rest of us,

Dear Peter Dalgaard, Brian Ripley, and R-Community,
My TypingErr:  ^50 is correct !
     It occured in just the first part of 'demo(graphics)'.
Yes!! After moving .RData away to .old.RData the error vanished !
  And yes, the .RData contained '... .Random.seed ... (seen by 'mc').
  But no, it dated '3 Feb ...', thus worked with R 1.2.1. and not
  about 0.63 .

  Many thanks for your very prompt answers at sunday evening !!

                                   Best - Hartmut Oldenbuerger

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:
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 biblioth?ques n?cessaires ? l'ex?cution
de cette application n'a pu ?tre trouv?e.
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 ?

Thanks in advance and best regards,

Renaud

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.

            

      
      
      
    

        
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 ....

Hi,

When I tried to run Rggobi a few weeks ago I had the same problem.  I then
read Nicholas Lewin-Koh's article on
http://www.public.iastate.edu/~nlewin/ggobi/Win-GGobi.html .  Then realised
that one need to have WinGGobi installed first, then modify C:\autoexec.bat
file, restart the machine (yeh that's the thing about Windows), then you
should be able to run it.

At least that is how I solved the problem...

I agree with Brian.
In fact after I got it running the speed is kind of slow.  I found that if
it better to just stick with the Win32 exe version, rather than calling it
from R.  Very often when I tried to call it from R my whole Window just
crashed, but then again it is the thing that often happens.

            

      
      
      
    

        
Yes I tried to subscribe to the list a few weeks ago and it refused my
subsription somehow...
