[R] rgraphviz problem

[Søren Højsgaard]

Perhaps you could try to see if you can get the 32 bit version to work AND you could also report the result of running sessionInfo() in your mail.
Regards
Søren

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
