RTextTools Beta Release

[Tim Jurka]

Hello Jon, John, Paul, and Anna!

The team has been working to prepare RTextTools for the Catania conference, and we now have a beta release ready for you to test out. We really appreciate your feedback; please let us know of any problems you encounter during the installation and testing process.

You can get started by visiting http://www.rtexttools.com/ . The "Documentation" section contains a rough draft of the user manual, along with a few example R scripts to help you begin.

Best,
Tim

Unfortunately I cannot get it to install. It fails configuring rJava.
Also, most unfortunately, it does not give any meaningful error messages
as to why it failed.

I tired it both with and without installing RTools. Note: my system
already has mingw64 installed, but I put the RTools before it on the
path. This didn't make any difference either.

I also have R installed on a Unix box at Temple. I'll try it on Tuesday.

Paul Wolfgang had the same problem, and I'll have to look into what's causing it. Loren... Wouter... any ideas?

Best,
Tim

I ran into something similar with rjava on windows. I can't remember how I installed it but I had to google around for a while. I've had rjava issues on each OS now so it's something endemic to that library. John, you around today? I could swing by later and see how to fix it.

Hi,

I went through the installation process on John's laptop (32 bit Windows 7, R 2.13.1). There are a few problems that arose.

1. rJava -- the installation problem here is that the computer needs to have the JDK Java developer toolkit. I downloaded version x86 here: http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u26-download-400750.html 

And here's the documentation.

http://www.oracle.com/technetwork/java/javase/documentation/install-windows-152927.html

Once that is installed then go to the r console and type install.packages('rJava') and it should install. You can check by typing library(rJava). If no error appears then you're good.

2. Dependencies. When I went to install RTextTools, there were a host of error messages indicating that many of the packages were not installing, so I manually installed most of them. Chief among the violators was the tm package. This seems weird to me but somehow R wasn't installing these correctly.

3. Maxent -- After I installed the Rtools.exe link, I then had to put Rtools and MinGW on the environment variable path. C:\Rtools\bin; C:\Rtools\MinGW\bin

Then everything worked and we are famous. Short end of this, with windows, I'm not sure if we can anticipate smart non-computer people to be able to install this as is, unless we have them follow these directions exactly.

I already have the JDK installed.

I'll try manually installing all the packages.

Hi Paul,

Thanks for your patience, and sorry about the hassle.  It goes with the territory, as you surely know better than I do!  Tim and Loren and Wouter are going great guns trying to get things sorted out.  In the meantime, let us know if you have luck with the manual install.

Cheers,
Amber

Yeah, this is a bummer... I was hoping rJava wouldn't be giving us so many problems. Loren, is it just boosting and bagging that use rJava? If so, there is a non-Java library for those two ( adabag - http://cran.r-project.org/web/packages/adabag/index.html ) and we might be able to find alternatives for any other Java alogrithms as well.

I think that is right -- the algorithms from the RWeka library are the ones that use rJava. But from what I recall rJava was used in some of the stemming, etc. from the 'tm' package. I should note, however, that with R.2.13 I did not have problems installing rJava on Mac. That may be because I had already installed the proper JDK but it also may be because the problem was solved with R.2.13 rJava version. I'm not particularly in the mood to investigate this issue at the moment, but it's something we can look at whilst in Catania.

Okay. I replaced the Snowball stemmers with Rstem which is written in C, so we might be able to eliminate rJava altogether.

[Loren Collingwood]

Nice. So why don't we work on that in Catania one night instead of going out drinking with the Europeans (besides I'm sure they don't want me to embarrass them). While we're at it, we can add in the LDA and those few other algorithms we haven't gotten around to.

Sounds like a plan... so drinking and coding instead? :)

Is there any other way?
