Hello,
When evaluating different learning methods for a categorization problem with
the (really useful!) caret package, I'm getting confusing results from the
Kappa computation. The data is about 20,000 rows and a few dozen columns,
and the categories are quite asymmetrical, 4.1% in one category a
fresh R and packages
install. No joy.)

someone else that can help or somewhere else I should be asking?
Thanks!

It's using Java and is rather over my head, but it seems to suggest that
something related to the content type might be wrong? Does this offer any
suggestions on how to fix my use of RGoogleDocs?

Hello,
Some code using RGoogleDocs, which had been working smoothly since the
summer, just stopped working. I know that it worked on November 3rd, but it
doesn't work today. I've confirmed that the login and password still work
when I log in manually. I've confirmed that the URL gives the same err

Hello,
I'm trying to figure out how to use the RGoogleDocs package from OmegaHat,
and am having a bit of trouble. I emailed Duncan Temple Lang directly, but
didn't receive a response, so I thought I'd try here to see if anyone else
can help.

This works perfectly (yay!): wine Z:/opt/OpenBUGS/winbugs.exe

Hi, I'm a new R user, coming from SPSS, and without a particularly strong

missing values. Here's the summary:
