[R] Text Mining in Non English Speaking Countries

[ziad.elmously]

Hello All,

I am interested in conducting text mining in languages other English.  My 
understanding is the following R packages can analyze alternative (to English) 
languages:


1.   "topicmodels"

2.   "snowball"

3.   "tm"

Can anyone confirm?  Specifically, I am interested in Hindi and Chinese (2 or 
so most popular dialects).  If so, can you recommend relevant documentation and 
share your experiences with these packages.

Thank you in advance.

Ziad Elmously

[R] Bayesian Belief Networks in R

[Ziad.Elmously]

Hello All,

 

Is anyone aware of an R package for Bayesian Belief Networks (BBN) that
can handle latent (hidden) nodes?  I am referring to process learning
the structure and the parameters of the model.  Based on the
documentation, the "bnlearn" package does not provide for such
capability.  In addition, is anyone aware of R packages that allow for
making inferences and sensitivity analysis for BBN?  Thank you in
advance.

[R] Trouble Runing R Version 2.13.0

[ziad.elmously]

To Whom It May Concern,

I have an R script that requires the Windows XP platform, version 2.13.0.  When 
launching R, however, I get the error message below:

Error in loadNamespace(name).  there is no package called "kernlab."
Unable to restore saved data in .RData.

Note that I also have version 2.15.0 installed and it works properly.

Your input would be greatly appreciated.

Thank you in advance.

[R] Running R from SAS

[Ziad.Elmously]

Hello All,
 
I am interested in running an R program with several random seeds.  One 
approach is to launch the program from SAS.  The recommended approach is to use 
the X command as shown below:
OPTIONS XWAIT XSYNC;

X "r.exe --no-save --quiet <""c:\temp\r\program.r"" >""c:\temp\r\program.log""";

However, this does not seem to work for me.  Does anyone know how to launch an 
R program from SAS?  Thank you in advance.

[R] rscaleUsage Function

[Ziad.Elmously]

To Whom It May Concern,

 

In using the Bayesm package titled "rscaleUsage," it does not reports
"mudraw," "taudramw," "sigmadraw," "Lambdadraw," and "edraw."  However,
it does not report the transformed y ratings or latent z scores.  Is
there any way to infer the value for y and z?
