[R] rgraphviz problem

[Anton Gerostathos]

Dear Søren,

thank you for the additional description. Through the link provided I got 
the idea to try the zip packages of Rgraphviz for installation. After an 
additional problem with the x64 version, finally resolved, I am now getting 
stuck with the following message when trying to load Rgraphviz:

Error in get(hookname, envir = env, inherits = FALSE) :
unable to allocate a memory bloc of 2.8 Go

any ideas?

Anton

Hello

I desperately need help with installing the Rgraphviz package under windows 
7.
Please forget my ignorance of basic topics, I’m a psychiatrist trying to use 
text mining to analyse psychiatric reports for criminal courts, statistics 
and machine learning are within my reach but R environnement subtleties not 
really...

I have read existing posts on rgraphviz installation problems that I have 
also encountered (i.e. R help - Rgraphviz installation problem) but after 
correcting these I get the following message  – differences from problem 
posted in bold :

Error : .onLoad failed in loadNamespace() for 'Rgraphviz', details:
call: value[[3L]](cond)
error: unable to load shared object
C:/Users/User/Documents/R/win-library/2.15/Rgraphviz/libs/x64/Rgraphviz.dll'
LoadLibrary failure: %1 is not a valid win32 application

I understand that the problem can be related to the x64 version. So I copied 
the i386 version of the library in the path mentionned, replacing the x64 
version, but new failure and same message received. I do not know how to 
change the path specified when loading rgraphviz neither whether this could 
change something.

I would really appreciate any kind of help

A Gerostathos
