caret::train() and ctree()
Like earth can be trained simultaneously for degree and nprune, is there a way to train ctree simultaneously for mincriterion and maxdepth? Also, I notice there are separate methods ctree and ctree2, and if both options are attempted to tune with one method, the summary averages the option it doesn't support. The full log is attached, and notice these lines below for

Error loading RMySQL
I have R 2.10.1 and 2.9.1 installed, and both have RMySQL packages installed. I script I'd developed using an older version (2.8.?, I think) used RMySQL too and an older version of MySQL (5.0.?), and worked fine at that time (about a year and a half ago +/- a month or two). But now, when I run it again, on new data, the script works fine until it is supposed to store its results in my DB.
