Running Redr

[BretIG]

Most likely really basic stuff here. Keep in mind I'm a market
researcher not a computer scientist.

I've installed the red-1.0-installer but am unable to get Redr to
run. When I click on the Orange Canvas icon, I get a Redr splash
screen, some text saying it's registering widgets, and then nothing
else happens....

Any thoughts?

Platform: WinXP

Can't make much of a guess without more information.

To find the error msg try opening redr within the python IDLE.

1) Open the IDLE. It should be under the python 2.5 directory in your
start menu
2) Within the IDLE File -> Open the main red module orngCanvas.pyw.
Default install path is C:\Python25\Lib\site-packages\orange
\OrangeCanvas\orngCanvas.pyw
3) New window should open with the module code. Run -> Run Module (or
F5) to execute the module
4) The error message should print in the main IDLE window

Can you post this error message. That should give us some clue as to
the problem.

Thanks,
Anup

Installed RedR. I already have R 2.9.0 running so i skipped the part
where it installs r2.7. Other than just clicked Next ...Next..Finish
for all modules.

When I launch it, I get only Bioinformatics tab. Is there an option I
missed out?

We are using rpy to access R through python, which requires a specific version of python and R. 

Since we are using python 2.5 the highest version of R that is supported is 2.7.0. Not finding the correct R version all the widgets will fail to load. 

The bioinformatics tab loads, because the widgets are from the original Orange framework (may or may not work ...). 

You should install R 2.7.0 separately and create a system variable 'RPATH' and set it to the home directory of R-2.7.0
(this is done by the default installer). 

We are working on updated to python 2.6 to get supported  for R-2.9.x.

I'm not sure the print out below will be of much use. Please let me
know what other steps I can take to assist in the diagnosis.

that is weird. 

The splash screen appears and a bunch of widgets are processed, but no application window appears afterwards?

Can you check the application data in your user directory, the default path is:

C:\Documents and Settings\[USERNAME]\Application Data\orange\OrangeCanvasQt4

There should be a file called outputLog.html. Maybe there are some clues in this log file. 

Thanks,

the outputlog.html is blank. I'll remove all components and reinstall.

Did the reinstall and all appears to be working.
