Correlation in Rattle

Hi Avideh,

Sorry to hear you're still having a problem. Tried usinging this two options on my 64-bit and 32-bit versions of R 2.15.0. Everything works fine. So I've at least been able to determine that there's nothing wrong with Rattle or with the combination of Ratttle and either the 64-bit and 32-bit versions of R 2.15.0. Beyond that, I'm not sure how much I can help you.

Tried to think of silly things that could be happening. So, for example, if you don't click on Settings -> Use Cairo Graphics Device, graphs generally get printed in R itself rather than on top of the Rattle graphical interface. If that were happening, then simply minimizing Rattle and looking at R would reveal the graph. I think this is unlikely though, given that you seem to be able to view graphs created using "Distributions" on the Explore tab.

The only thing I can think of other than that is that maybe there is something wrong with your installation of R or with the process you're using to install Rattle. I don't recall there being anything tricky about installing either R or Rattle though. So I don't know what the problem could be.

You could try contacting Graham Williams to see what he suggests. Or you could turn this over to an IT person if you have one.

Sorry I can't be of more help.

Paul

Hi Paul,


Thank you so much for you response. I tried using the Weather data and still had the name problem. I also removed the package and reinstalled it and no luck with that either. All the other commands work, the only 2 that do not work are Correlation and Principal Components. When I select either of them and click Execute absolutely nothing happens, I don't even get a warning message. I am working on a new project and since I don't have a great knowledge of R programing I am highly dependent on Rattle and it really bothers me that these two commands are not working for me.


I hope we could resolve this issue.


Best Regards,
Avideh

Hi Avideh,

I have Rattle installed on the 64-bit version of R 2.15.0 and this seems to work OK. I had a dataset of my own loaded into Rattle when I saw your email. Tried creating the plot using these data but got a warning saying I should limit the number of variables to 40. So I changed to the weather dataset that comes with the software (which has fewer variables) and everything worked fine.

Do you have a lot of variables in your data? What happens when you try this using the weather dataset? If you're unfamiliar with the weather dataset, you can load it by launching Rattle and then clicking execute.

If there really is a problem, maybe uninstalling and reinstalling Rattle would fix it? For uninstall, you can use code like: remove.packages("rattle"). For re-install, you could use code like: install.packages("rattle", dependencies = TRUE).

HTH,

Paul
