[Rd] object not found whilst loading namespace

[Max Kuhn]

Please disregard the last email...

The issue was a syntactical error in a file that, alphabetically,
comes before confusionMatrix.R in the package.

The odd thing was that the problem in this file did not throw and
error (or I would have easily found it). I decided to source the R
files one by one to see if there were any issues and that showed the
problem:

> source("~/Code/caret/pkg/caret/R/classLevels.R")
Error in source("~/Code/caret/pkg/caret/R/classLevels.R") :
  ~/Code/caret/pkg/caret/R/classLevels.R:150:0: unexpected end of input

Thanks anyway,

Max
